The severe charge recombination and the sluggish kinetic for oxygen evolution reaction have largely limited the application of hematite (α‐Fe2O3) for water splitting. Herein, the construction of Cu2S/Fe2O3 heterojunction and discover that the formation of covalent SO bonds between Cu2S and Fe2O3 ca...
