摘要

Precise regulation of the surface morphology and structure of reaction electrodes, along with enhanced charge transfer and catalytic activity, is essential for ensuring the efficient progress of the electrocatalytic hydrogen evolution reaction (HER). In this work, a Co–Ce dual-synergy strategy combined with a metal–organic framework (MOF) and phosphorization process was employed to achieve the above objective, and a systematic investigation was conducted on the phase composition, microstructure, and electrocatalytic performance of the MOF-derived sea-urchin-like electrocatalyst. The results demonstrated that although the electrode modified by Co–Ce dual synergy and MOF phosphorization involved a more complex preparation process, it effectively promoted charge transfer, increased the electrochemically active surface area, and significantly enhanced the catalytic activity and stability for HER. This study provides theoretical guidance and technical reference for the design and practical application of high-performance HER electrocatalysts.
