Enhanced photocatalytic activity for degrading pollutants of g-C3N4 by promoting oxygen adsorption after H3BO3 modification

- G-C3N4 is modified by a hydrothermal post treatment with orthoboric acid.
- The surface modification could enhance the separation of photogenerated charges.
- This leads to the enhanced photocatalytic activities for degrading pollutants.
- The borate acid modification favors O2 adsorption to promote charge separation.
