- •
Implantation of p-type Mn3O4 on the surface of ZnO enhance the photocatalytic activity in natural sunlight.
- •
The charge transfer synergy between the p-type Mn3O4 and n-type ZnO conformed the generation of ROS in the system.
- •
Superoxide anion (O2●−) radicals are the major contributors in removal process.
- •
Priority interaction of ROS with the substrates rather than intermediates.
- •
Cl− and Br− serves as facilitators in the degradation process.
