“…Determining the nature of active sites is important for designing highly active and stable ORR electrocatalysts. 203,204 Therefore, the development of in situ characterization techniques is very important to explore the active sites and reaction mechanisms of electrocatalysts. In addition, by combining these with DFT calculations, the entire electrocatalytic reaction process can be understood more clearly and accurately, and help to make practical predictions.…”
The mechanisms, synthesis methods and strategies for application of W/Mo-based ORR electrocatalysts are briefly introduced. Recent advances in W/Mo-based ORR electrocatalysts are discussed in detail.
“…95,96 By optimizing the interface interaction, the corrosion resistance and catalytic reaction efficiency of the catalyst were enhanced, and the thermal stability and oxidation resistance of the catalyst were improved to achieve an efficient and stable hydrogen evolution reaction. 97–99 These advantages make interface regulation a crucial strategy for designing catalysts with high performance and stability. The interaction between the interface can be optimized using interface control strategies, which can enhance electron transport and reactivity.…”

Renewable energy electrolysis of water to produce hydrogen is an effective measure to break energy dilemma. However, achieving activity and stability under high current density is still a key problem...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
