Abstract

Reversible conversion of Cu²⁺ and Cu⁺ under illumination and with oxidation is demonstrated over Cu_xO/SrTiO₃. Such Cu²⁺/Cu⁺ homeostasis together with its photosensitizer function and p-n heterojunction formation has lead to highly active and stable visible photocatalytic performance. This strategy will provide some new insights into the design of highly efficient photocatalysts.
