摘      要：In this work,platinum group metal-free(PGM-free)electrocatalysts were synthesized,characterized,and tested for hydrogen evolution reaction(HER).These materials were mono-,bi-and trimetallic Ni-based electrocatalysts with the addition of a second or a third transition metal(TM),such as iron and ***–phthalocyanine(TMPc)was used as a metal precursor,mixed with a conductive carbon backbone and subjected to pyrolysis under controlled temperature and atmosphere *** temperatures of pyrolysis(600℃ and 900℃)were *** effect of TM loading in the precursors,different pyrolysis temperatures on the surface chemistry and morphology,and electrocatalytic activity towards HER were *** increase of NiPc in the initial mixture is beneficial to improving the electrocatalytic *** addition of a second and a third metal reflects positively on the HER ***,the pyrolysis temperature influences both the formation and growth of the nanoparticles,and this information is supported by high-resolution transmission electron microscopy(HR-TEM)and light synchrotron X-ray absorption spectroscopy(XAS)measurements.
