Abstract Efficient and sustainable energy development is a powerful tool for addressing the environmental crises. Single‐atom catalysts (SACs) have received high attention their extremely atom utilization efficiency excellent catalytic activity, broad application prospects in chemical production. M‐N 4 an active center model with clear but its properties such as selectivity, durability need to be further improved. Adjustment of coordination environment central metal by incorporating heteroatoms (e.g., sulfur) effective feasible modification method. This paper describes precise synthetic methods introducing sulfur atoms into controlling whether they are directly coordinated form specific configuration, sulfur‐doped carbon‐based single‐atom electrocatalytic reactions ORR, CO 2 RR, HER, OER, other reaction systematically reviewed. Meanwhile, effect tuning electronic structure ligand configuration parameters due doped improvement performance introduced combining different characterization testing methods. Finally, several opinions on SACs put forward.

Nitrogen doping has become a fundamental approach to enhance the catalytic performance of carbon materials across various applications. The introduction nitrogen creates defects and active sites, promoting formation small metal particles strengthening metal–support interaction within materials. However, challenge lies in developing sustainable cost-effective methods for synthesizing nitrogen-doped In this study, we present synthesis ruthenium on catalysts (Ru-CCP) using chitosan as source. Unlike traditional methods, our process avoids use additional precursors templates, streamlining while renewable resource. synthesized material exhibits an exceptional electrochemical hydrogen evolution reaction (HER) alkaline conditions by achieving current density 25 mA cm–2 at impressively low overpotential 46 mV, outperforming Pt/C under similar conditions. detailed studies structural electronic properties X-ray absorption spectroscopy (XAS), photoelectron (XPS), diffraction (XRD), transmission electron microscopy (TEM) revealed that remarkable activity is upheld unique interplay between Ruδ+ surface moieties, notably pyridinic pyrrolic nitrogen. Here, demonstrate control particle size environment around atom via unravel role tuning performance. addition, work offers insights into efficient HER catalyst design emphasizes potential biomass-derived like advancing clean production energy

Abstract Constructing structural defects is a promising way to enhance the catalytic activity toward hydrogen evolution reaction (HER). However, relationship between defect density and HER has rarely been discussed. In this study, series of Pt/WO x nanocrystals are fabricated with controlled morphologies densities using facile one‐step wet chemical method. Remarkably, compared polygonal star structures, dendritic ( d ‐Pt/WO ) exhibited richer density, including stepped surfaces atomic defects. Notably, catalyst required 4 16 mV reach 10 mA cm −2 , its turnover frequency (TOF) values 11.6 22.8 times higher than that Pt/C under acidic alkaline conditions, respectively. addition, //IrO 2 displayed mass 5158 mg Pt −1 at 2.0 V in proton exchange membrane water electrolyzers (PEMWEs), which significantly commercial Pt/C//IrO system. Further mechanistic studies suggested reduced number antibonding bands lowest dz ‐band center, contributing adsorption release solution. The highest center facilitated from molecules dissociation medium. This work emphasizes key role improving electrocatalysts.
