Photocatalytic oxidation of benzene to phenol using molecular O2 is one the most promising sustainable approaches for green synthesis phenol. Introducing oxygen vacancies (OVs) on semiconductor surfaces by defect engineering a strategy enhance efficiency produce due unique functions OVs in facilitating charge separation and activation O2. Herein, vacuum-sealed annealing has been well developed generate abundant surface semiconductors, such as WO3. The well-sealed quartz vial creates well-controlled low-pressure condition formation without need external energy maintaining vacuum state. Moreover, gaseous species generated during thermal process help mitigate stress-induced defects, particularly bulk defects. annealed WO3 with sufficient reduced defects shows better photocatalytic performance one-step O2, compared synthesized through Ar H2 atmospheres. present found be further applicable engineer wide range semiconducting photocatalysts optimize their properties efficient photocatalysis other OV-promoted systems.
