I have followed the procedure outlined in the article titled "One-step thermal polymerization synthesis of nitrogen-rich g-C3N4 nanosheets enhances photocatalytic redox activity" by Pang et al. (2022) to produce nitrogen-rich g-C3N4. The authors specify that the thermal polymerization should be conducted at 550°C. However, upon attempting the same procedure, all of the materials dispersed and there was no residue left. Esteemed researchers, could you please advise on how to resolve this issue? Your assistance in addressing this matter is greatly appreciated.
