Abstract:
Reversible conversion of Cu2+ and Cu+ under illumination and with oxidation is demonstrated over CuxO/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.
