The exceptional photo-catalytic activity of ZnO/RGO composite via metal and oxygen vacancies

- ZnO/RGO composite with zinc and oxygen vacancies was successfully synthesized.
- ZnO/RGO composite exhibited exceptional photocatalytic activity.
- The presence of both zinc and oxygen vacancies caused effective charge separation.
- Holes and electrons were trapped by VZn acceptor and VO donor respectively.
- H+ and OH enhanced the photoactivity of ZnO/RGO as the photocatalyst.
