摘要:
Replacing anodic oxygen evolution reaction (OER) by urea oxidation reaction (UOR) provides a feasible approach to achieve high-efficiency hydrogen (H2) generation. However, the design of a robust catalyst for urea-assisted H2 generation remains a difficult problem. In this study, an innovative strategy to integrate bimetallic spinel sulfides CoNi2S4 nanosheet arrays with graphitized carbonized wood (denoted as CoNi2S4/GCW) for synergistically optimizing the electroconductivity and the hierarchical porous structure of the CoNi2S4/GCW catalyst is...
