Co-MOF as a sacrificial template: manifesting a new Co3O4/TiO2 system with a p–n heterojunction for photocatalytic hydrogen evolution

A MOF derived approach to synthesize a Co₃O₄/TiO₂ heterostructure with p-type spinel-Co₃O₄ and n-type anatase TiO₂ for enhanced photocatalytic H₂ evolution by water splitting.
