Flower-like Co3 S4/NiSx Heterostructure as an Efficient Electrocatalyst for Oxygen Evolution Reaction
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.
