Enhancement of visible light photocatalytic activities via porous structure of g-C3N4

- Porous g-C3N4 was prepared by novel bubble template method.
- The surface area and the porous structure of g-C3N4 were successfully controlled.
- The visible photocatalytic activity of g-C3N4 was greatly enhanced.
- Degradation pathways of organic pollutants was not changed by the porous structure.
