Interfacial P-O-Cu Bonds Drive Rapid Z-Scheme Charge Transfer for Efficient Photocatalytic O₂ Evolution Synchronized with Cr(VI) Reduction.

ABSTRACT: Addressing the challenges of energy production and environmental sustainability necessitates the development of advanced materials capable of facilitating both photocatalytic reduction and oxidation processes. Here, we report a Z-scheme Ag₃PO₄/CuBi₂O₄ heterojunction photocatalyst, which was fabricated via the in situ anisotropic growth of Ag₃PO₄ nanoparticles on the ends of CuBi₂O₄ microrods. The prepared heterojunction exhibits a low lattice mismatch (~3%) and features a covalently bonded interface, anchored by oxygen atoms, with the formation of P-O-Cu bonds. This interface synergizes with the built-in electric field to drive an efficient Z-scheme charge transfer mechanism, significantly enhancing the
