Dual defect sites at g-C 3 N 4 synergistically induce the electron localization effect for boosting photocatalytic H 2 O 2 production

Defect engineering (such as doping of non-metallic elements or vacancies) is a universally effective modification to improve the electronic structure and physical properties of g-C 3 N 4 , which has been widely applied in various photocatalytic systems.
