摘要
异质结独特的物理和化学性质为电催化析氧提供了广阔的应用空间.采用两步水热法在泡沫镍上制备了自支撑的花状Co3S4/NiSx异质结催化剂,使用聚合硫作为硫源,通过原位硫化制造了界面丰富的异质结结构,将其作为电催化材料能在碱性溶液中表现出优秀的析氧性能.研究成果为设计高效异质结电催化析氧材料提供了有效策略.
Abstract
The unique physical and chemical properties of heterostructure can offer large space for electrocatalytic oxygen evolution.In this paper,a self-supporting flower-like Co3S4/NiSx heterostructure catalyst was prepared on nickel foam by a two-step hydrothermal method.The heterostructurec with rich interfacial interface was obtained by in situ vulcanization of polymerized sulfur,which showed excellent oxygen evolution performance in alkaline solution as electrocatalytic material.Interfacial engineering through heterostructures can provide an effective strategy for new inspiration for designing advanced OER electrocatalysts.
