Abstract
Abstract To meet the practical demand of overall water splitting and regenerative metal–air batteries, highly efficient, low‐cost, and durable electrocatalysts for the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) are required to displace noble metal catalysts. In this work, a facile solid‐state synthesis strategy is developed to construct the interfacial engineering of W 2 N/WC heterostructures, in which abundant interfaces are formed. Under high temperature (800 °C), volatile CN x species from dicyanodiamide are trapped by WO 3 nanorods, followed by simultaneous nitridation and carbonization, to form W 2 N/WC heterostructure catalysts. The resultant W…
