Visible-light-induced water oxidation by a hybrid photocatalyst consisting of bismuth vanadate and copper(ii) meso-tetra(4-carboxyphenyl)porphyrin

Abstract

Copper(II) meso-tetra(4-carboxyphenyl)porphyrin surface-modified monoclinic scheelite bismuth vanadate (CuTCPP/BiVO₄) has been synthesized via a two-step route involving chemisorption of TCPP on BiVO₄ and successive Cu(II) ion incorporation into the TCPP, and the surface modification drastically enhances the water oxidation to oxygen (O₂) under visible-light irradiation (λ > 430 nm).
