摘　　要：开发制备高性能复合材料电催化剂提升海水裂解性能,对于氢能的高效发展具有重要的意义。采用两步法设计合成了以Ce-MOF为部分牺牲模板材料的三金属纳米棒催化剂(Ce-MOF@CoNiCeLDH),并利用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射(XRD)及X射线光电子能谱(XPS)对合成的Ce-MOF@CoNiCeLDH催化剂进行了全面的形貌、结构和电子环境分析。同时,合成了不同元素比例的Ce-MOF@CoNiCeLDH催化剂,结果表明当Co和Ni摩尔比为3:1时,在Ce、Co、Ni三金属氢氧化物与Ce-MOF的协同作用下,Ce-MOF@CoNiCeLDH表现出最佳的海水OER的性能。The development and preparation of high-performance composite electrocatalysts to improve the overall electrochemical seawater water splitting is of great significance for the efficient development of hydrogen energy in seawater.Ce-MOF based CoNiCe trimetallic hydroxide nanorod catalysts(Ce-MOF@CoNiCeLDH)were designed and synthesized using a two-step method,and Ce-MOF@CoNiCeLDH catalyst was characterized by scanning transmission electron microscopy(SEM),transmission electron microscopy(TEM),X-ray diffraction(XRD)and X-ray photoelectron spectroscopy(XPS)for morphology,structure and electronic environment analysis.Meanwhile,Ce-MOF@CoNiCeLDH catalysts were synthesized in this study and selected by electrochemical experiments.The results showed that when the molar ratio of Co to Ni was 3:1,the Ce-MOF@CoNiCe LDH exhibited the best performance for OER under the synergistic effect of Ce,Co and Ni tri-metallic hydroxides and Ce-MOF.
