Key Ideas
- Researchers at the Chinese Academy of Sciences developed a high-entropy nanostructured catalyst for efficient hydrogen production and glycerol chemical synthesis.
- The catalyst demonstrated exceptional selectivity for glycerate production and remarkable stability during electrolysis, maintaining high performance for over 210 hours.
- This study represents a sustainable and efficient approach towards green hydrogen production and high-value chemical synthesis, contributing to carbon neutrality goals.
A research group led by Prof. CHEN Liang at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has designed a high-entropy electrocatalyst that enables efficient production of hydrogen and valuable glycerol chemicals. Published in Nature Nanotechnology, the study addresses the challenge of low activity and high overpotential of oxygen evolution reactions (OERs) during water electrolysis for hydrogen production. The developed high-entropy nanostructured PtCuCoNiMn catalyst enhances both activity and selectivity for glycerate production, demonstrating exceptional performance at high current densities. The catalyst also exhibited remarkable stability in electrolysis settings, showcasing high-performance glycerol electro-oxidation reactions for over 210 hours. This innovative approach not only enables green hydrogen production but also synthesizes high-value chemicals through electrocatalysis, contributing to sustainability goals such as carbon peaking and neutrality.
