The oxygen vacancy (Vo) is closely related to the activity of hydrogen evolution reaction (HER) in electrocatalysts. However, the role of vacancy defects and their concentration effects remain unclear. Here, we selected Bi₂O₃ as a model, which is an unfavorable electrocatalyst for HER due to its non-ideal Gibbs free energy of hydrogen adsorption (ΔGₕ), to … Read more
Due to the different reaction mechanisms of the Ammonia Oxidation Reaction (AOR) and Hydrogen Evolution Reaction (HER), there is currently a lack of dual-function catalysts that can effectively catalyze both reactions. In this study,we used NaH2PO2 as the phosphorus source to dope phosphorus (P) into the PtZn alloy through calcination, inducing lattice strain in platinum … Read more
High-entropy alloys (HEAs) have become promising candidate materials for hydrogen evolution reaction (HER) electrocatalysts due to their unique cocktail electronic effect and lattice distortion effect. In this study, ultra-small (less than 2 nanometers) nanoparticles of PtRuCoNiCu HEA were highly dispersed on hierarchical nitrogen-doped carbon nanocages (hNCNC) through a low-temperature thermal reduction method, referred to as … Read more
