Electrochemical water splitting is one hopeful strategy for hydrogen production, and designing efficient hydrogen evolution electrocatalysts under universal pH is one of the most critical topics. Here, we have successfully prepared mesoporous bimetallic core–shell nanostructures with Au nanowires (Au NWs) as cores and mesoporous Rh as shells (Au@mRh NWs). Due to the one-dimensional structure and mesoporous core–shell structure, Au@mRh NWs possess more active sites and provide the synergistic effect, leading to the great improvement of the electrochemical activity toward the hydrogen evolution reaction under a wide range of pH. The present work proposes a versatile strategy for preparing a bimetallic core–shell structure with a mesoporous shell, which is highly promising for more electrocatalytic applications.

We have reported flexible synthesis of Au@Pd core–shell mesoporous nanoflowers for the methanol oxidation reaction with excellent performance.

Current methods for industrial-scale ammonia synthesis rely excessively on fossil fuels, causing severe CO2 emissions. Electrochemical nitrogen reduction reaction (NRR) is a sustainable and environmentally friendly technology for ammonia synthesis...
