Constructing structural defects is a promising way to enhance the catalytic activity toward the hydrogen evolution reaction (HER). However, the relationship between defect density and HER activity has rarely been discussed. In this study, a series of Pt/WOx nanocrystals are fabricated with controlled morphologies and structural defect densities using a facile one‐step wet chemical method. Remarkably,...
Rationally integrating multi‐active sites into one ideal catalyst is an effective approach to accelerate multistep reactions by synergic catalysis. Herein, a universal and facile room temperature impregnation strategy is developed to construct Ru atomically dispersed catalyst (Ru ADC) with Ru‐C5 single atoms and Ru oxide nanoclusters (≈1.5 nm), which can also be extended to prepare Ir, Rh, Pt, Au,...
Rational design of low‐cost, highly efficient, and stable electrocatalysts for the hydrogen evolution reaction (HER) has attracted wide attention. Herein, 3D RuCu nanocrystals (NCs) are successfully synthesized by a facile wet chemistry method, in which amorphous RuCu nanosheets are directly grown on crystalline Cu nanotubes (NTs). Importantly, the obtained 3D RuCu NCs only need 18 and 73 mV to deliver...
