摘要

贵金属如Pt/C、RuO₂等一般被认为是优异的电催化剂,但是高成本限制了其发展,因此寻求低成本且高性能的非贵金属催化剂来代替贵金属催化剂成为近年来的研究热点。设计并制备了一种新颖的NiCoP阵列:来源于泡沫镍基底的镍离子与引入的钴离子经水热-磷化处理后形成。NiCoP阵列由于其独特的片状交叉形貌以及磷化后形成的较多孔洞,使其具有较大的比表面积和暴露出更多的活性位点,进而促进水的电解,在碱性溶液中展现出优异的催化性能。在1.0mol/L KOH电解液中,电流密度为20mA/cm²时,全解水电压仅为1.70V,是一种优异的双功能电解水催化剂。

Abstract

Precious metals such as Pt/C and RuO₂ are generally regarded as superior electrocatalysts,but high costs have limited their development.Therefore,the search for lowcost and high performance non-noble metal catalysts to replace precious metal catalysts has become a research hotspot in recent years.A novel NiCoP arrays were designed and prepared.The Ni ions were provided by the foamed nickel base and formed NiCoP arrays with the added Co ions through hydrothermal-phosphating.NiCoP arrays had large specific surface area,and exposed more active sites due to the unique lamellar cross morphology and the formation of more holes after phosphating.Therefore,they can promote overall water splitting,and exhibited excellent catalytic performance in alkaline solution.In 1.0mol/L KOH electrolyte,when the current density was 20mA/cm²,the potential of overall water splitting was only 1.70V,which made NiCoP arrays became excellent dual-function electrocatalysts.
