Nitroreductases, present within both prokaryotes and eukaryotes, form a group of flavin‐dependent enzymes capable of reducing nitro compounds using NAD(P)H as reducing agent. These enzymes have been widely studied due to their diverse roles in bioremediation, cancer therapy, cell ablation, and antimicrobial resistance. In recent times, the versatility of nitroreductases has been expanded towards the synthesis of highly valuable compounds such as aromatic and aliphatic amines, azoxy‐ and azobenzenes, as well as N‐heterocycles. This review examines the biological role and diversity of flavin‐dependent nitroreductases, and highlights their current and potential future application as biocatalysts for the sustainable synthesis of nitrogen‐containing pharmaceutical compounds and bulk chemicals.

Abstract The hierarchical ZSM‐5 zeolite, which contains mesopores in addition to intrinsic micropores, is expected to enhance the bulky molecular diffusion and accessibility of acid sites. These sites, distributed in the internal surface (micropore) or external environment (including external surface and mesopore walls), play different roles in chemical reactions. To explore the effect of internal/external acidity on the reaction, in this study, a series of hierarchical ZSM‐5 zeolites with similar pore structures but different external acid properties were synthesized. Tartaric acid was employed to poison the acidic sites in the external environment selectively and extract Al from the framework. The catalytic cracking of n ‐heptane (the main compound of naphtha) was chosen as a model reaction. The results show that elimination of external active sites tends to reduce the coke formation. The more external acid sites are selectively eliminated, the better catalytic performance can be achieved because of suppressing the bimolecular reactions of ethylene and propylene.

Abstract Several ceria‐zirconia supported mono and bi‐metallic transition metal oxide clusters containing Fe, Cu, and Ni are synthesized by dry impregnation. Through XRD, H 2 ‐TPR, NH 3 ‐TPD, pyridine adsorption followed by FTIR spectroscopy and XAS, the well‐dispersed nature of the transition metal oxide clusters is revealed, and the Lewis acidity of the catalysts is assessed. In‐situ FTIR spectroscopy is used to monitor the methane activation on catalyst surfaces. All catalysts activate methane at 250 °C forming methyl, alkyl, and methoxy species on the catalyst surface. By co‐feeding steam and oxygen together with methane, continuous direct oxidation of methane to methanol can be achieved, with the complete oxidation to CO 2 as the other reaction path. Methoxy species are found to be a key intermediate for methanol production. Lowering the methane conversion improves the methanol selectivity. By extrapolation, it is estimated that methanol selectivity close to unity can be achieved below a threshold of methane conversion at about 0.002 %. The formation of CuO and NiO mixed metal oxides produces stronger Lewis acid sites and yields higher methanol selectivity.

Abstract Selective electrosynthesis of urea from carbon source (CO 2 ) and nitrogen (N 2 , NO 3 − , NO 2 − ) source provides a sustainable strategy for production of essential nitrogen‐based fertilizers. The traditional technology of urea synthesis employs two consecutive processes, synthesis of NH 3 from N 2 +H 2 and urea from NH 3 +CO 2 , which always involves high energy consumption and environmental concerns. By contrast, urea electrosynthesis avoids the above harsh steps and meanwhile has higher atomic economy. Herein, we present a comprehensive review on the progress and prospect of urea electrosynthesis from abundant carbon and nitrogen sources via coupling of C−N under ambient conditions, and also discuss the mechanism researches, strategies of substrates activation, current challenges and future opportunities of urea electrosynthesis. The urea electrosynthesis via C−N coupling realizes abundant and low‐cost inorganic carbon and nitrogen sources for efficient resource utilization and provides guidance and reference for C−C, C−S or other coupling reactions.

Iron‐catalyzed C−H amination is emerging as an attractive and sustainable method to install amine functionalities into organic compounds. Amination of C(sp3)−H bonds is usually mediated by an iron‐nitrene intermediate via a Hydrogen Atom Abstraction/Radical Recombination mechanism reminiscent of biomimetic C−H oxidation. Accordingly, this transformation can be catalyzed by engineered iron enzymes, heme and nonheme iron complexes as well as iron salts, although it is often limited to intramolecular reactions and/or activated positions. Aromatic C(sp2)−H amination is mediated by addition of electrophilic iron nitrenes or protonated N‐radical intermediates (produced with Fe catalysts) to aromatic systems. Again, high selectivity is obtained via (pseudo) intramolecular reactions. From a mechanistic perspective, several iron nitrene intermediates have been isolated and characterized over the years in different ligand scaffolds and iron oxidation states. Structure‐activity correlations have been drawn only in few cases and point to a key role of the spin density on the nitrene ligand and of the iron oxidation state. This review describes the state of the art for homogeneous iron catalyzed C(sp3)−H and C(sp2)−H amination focusing on the last 5 years (2019–2023) from a mechanism‐driven catalyst design perspective.

We describe a new type of cooperative phenomenon, which we term as the dynamic synergistic cooperation, that can be found in the Pt‐skin Au‐core catalyst. The phenomenon entails three key aspects, namely, (i) a high catalytic activity at Au‐rich surface sites resulting from synergistic effect, (ii) ultrafast Au or Pt segregation effect driven by the mobile adsorbed species, like CO and O, and (iii) dynamic coupling between these two effects. The nature of the catalyst surface during the catalytic CO oxidation reaction (COR) is investigated using a combination of density functional theory (DFT) and kinetic Monte Carlo (KMC) methods. The Pt‐skin Au (111) surface is shown to be composed of a transient patchwork of surface structures, some of which are Pt‐rich and others Au‐rich. These surface structures submerge/resurface at the sub‐reaction timescales in response to the movement of the adsorbed species, which causes the nature of a catalytic site to change with time. The reaction turnover frequency (ToF) is among the emergent properties resulting from the cooperative phenomenon.

Photocatalytic hydrogen evolution via water splitting is considered as one of the most promising sustainable energy supply strategies. The cocatalyst loading method is widely applied to overcome the inefficient charge separation and sluggish surface hydrogen evolution reaction (HER) of photocatalysts. Herein, we prepared the Ru‐doped NiFe layered double hydroxide (NiFe‐LDH) as a cocatalyst for g‐C3N4. We find the photocatalytic HER activity of g‐C3N4 is obviously enhanced by the loading of Ru‐doped NiFe‐LDH, the H2 evolution rate reaches 32 µmol/h about 5 times higher than original NiFe‐LDH loaded one. Our experimental and theoretical studies reveal that the synergistic effect of NiFe‐LDH matrix and Ru dopant is the key reason for the improved photocatalytic activity, where the NiFe‐LDH matrix promotes charge separation and transfer, the Ru dopant synergistically lowers the energy barrier for surface H2 evolution reaction, then achieving excellent photocatalytic H2 evolution activity.

Red mud (RM), the waste of the Bayer process for aluminum production, is mostly stored in landfill areas, creating serious environmental and economic problems. It offers substantial potential for catalytic applications, mostly because of its cost efficiency and rich chemical composition, including the oxides of Fe, Si, Al, and Ti. Using RM as a catalyst not only contributes to environmental protection but also offers economic advantages as it can potentially reduce the reliance on expensive noble metals typically used in solid catalyst formulations. RM is predominantly used in thermal‐ and photo‐catalysis, serving as a bulk catalyst, support material, promoter, additive, or as a host material for heterojunction catalysts. Prior to use, RM is generally modified to enhance its textural properties and tailor its composition. This review provides a comprehensive analysis on the utilization of RM in catalytic applications. The structural changes resulting from various pretreatments and their impact on catalytic properties are discussed. Key thermal‐ and photo‐catalytic reactions involving the use of RM‐based catalysts are presented to highlight their industrial and environmental potential. Potential pathways for further optimization of RM‐based catalysts are also proposed, offering a broad perspective on future directions in the field.

The utilization of renewable energy for electrocatalytic CO2 reduction (CO2RR) represents a significant advancement in green carbon conversion technologies. Single atom catalysts (SACs) featuring a transition metal‐nitride‐carbon (M‐Nx‐C) architecture exhibit catalytic activity for the reduction of CO2 to CO. However, the impact of the morphology of carbon supports, particularly their pore structure, on the electrocatalytic performance of CO2RR warrants further investigation. In this study, we fabricated a series of Ni‐based SACs supported by porous carbon nanofibers through electrospinning and sacrificial template method. We examined variations in microstructure of these porous carbon nanofiber carriers at different pyrolysis temperatures and elucidated their effects on CO2RR catalytic performance. The catalyst obtained at 1000 °C demonstrated efficient electrocatalysis for converting CO2 to CO due to its large specific surface area, abundant hierarchical pore structure, and high content of Ni‐Nx species resulting from both the sacrificial template method and high‐temperature pyrolysis. A Faradaic efficiency exceeding 90% was sustained across potentials ranging from −0.7 V to −1.3 V (vs. RHE), with a peak efficiency reaching 96.1% at −1.0 V (vs. RHE). Kinetic analysis indicated that this sample exhibited the highest reaction kinetics alongside minimal charge transfer resistance.

We introduce an environmentally friendly one‐pot approach for the efficient synthesis of functionalized tri(furyl)methane (TFM‐x). This method involves the reaction of biomass‐derived furans such as furfural (FAL), functionalized FAL or 5‐hydroxymethylfurfural (HMF) with 2‐methylfuran (2‐MF) using a cost‐effective 2‐hydroxy‐N,N‐dimethylethane‐based acidic ionic liquid (AIL) catalyst. AIL catalyst at 60 °C showed a high yield of TFM‐OH and TFM‐CHO with complete conversion of the furan‐containing aldehyde functional group with nearly 95% product selectivity. In addition, the TriM‐x synthesis under optimized conditions were performed without using solvent. The different 2‐[bis‐(5‐methylfuran‐2‐yl)methyl]‐5‐hydroxyfuran (TriM‐OH) and 2‐[bis‐(5‐methylfuran‐2‐yl)methyl]‐5‐furaldehyde (TriM‐CHO) were then employed for electrochromic applications, with TriM‐OH demonstrating a higher coloration efficiency than TriM‐CHO.
