Interface Engineering in CoP/CePO4 Derived from a Prussian Blue Analogue as a Highly Efficient Electrocatalyst for Alkaline Hydrogen Evolution Reaction
ChemElectroChem(2021)
Abstract
AbstractIn this work, engineering a heterostructural interface into a CoP/CePO4 hybrid has been achieved from a pre‐designed Co‐PBA/CePO4 precursor. The new CePO4 engaged interface can regulate the electronic structure of the active CoP as well as enhance the intrinsic activity. As a result, the porous CoP/CePO4 material shows a superior electrocatalytic performance toward hydrogen evolution reaction (HER) with a lower overpotential of 162 mV to reach a current density of 10 mA cm−2 and a low Tafel slope of 48.7 mV dec−1. This research could widen the way of engineering heterostructural interfaces with a facile method and promote the exploration of MOF‐derived heterostructural electrocatalysts.
