Heterointerface‐Rich Ni3N/WO3 Hierarchical Nanoarrays for Efficient Glycerol Oxidation‐Assisted Alkaline Hydrogen Evolution

Glycerol oxidation-assisted water electrolysis has emerged as a cost-effective way of co-producing green hydrogen and HCOOH. Still, preparing highly selective and stable nickel-based metal electrocatalysts remains a challenge. Herein, heterostructure Ni
