The photoreduction of CO 2 has attracted extensive attention as a promising solution to global warming. In this study, Cu‐modified TiO (B) (CuTB) nanoflowers with oxygen vacancies (OVs) are designed and synthesized via hydrothermal treatment photodeposition promote the reactivity selectivity reduction under visible light. CH 4 yields sample Cu 1 TB‐1.5 light 5.72 0.02 μmol g −1 h , wherein yield was 15.5 times that TB; its is 99.6%, cycling stability excellent. OVs can broaden absorption TB region, promotes photoinduced electron transfer from species act an active center. synergistically enhance charge separation, adsorption, conversion. facilitates formation intermediate COOH* during photocatalytic process, thus improving CO. This research provides unique idea for development novel highly selective photocatalysts.
