Advanced Functional Materials, Год журнала: 2024, Номер 34(46)

Опубликована: Июнь 25, 2024

Abstract In this work, self‐derivation and surface reconstruction strategies are innovatively introduced into the synthetic route of metal complex‐derived catalysts. The in situ grown nanorod arrays Ni‐based complex prepared by a simple rapid ligand chelation reaction. Furthermore, highly active heterogeneous electrocatalysts developed mild‐temperature calcination. Attributed to maintained morphology dispersed Ni/Ni(OH) 2 heterojunction sites, as‐prepared electrode exhibits superior hydrogen evolution activity (38.4 mV–10 mA cm −2 ). particular, dynamic during oxygen through Fourier transform infrared Raman spectroscopies observed. reconstructed Ni(OH) /NiOOH activation gives higher performance (369 mV–200 Further density functional theory mechanism studies disclose that contributes adsorption H* activated optimizes formation intermediates evolution.
