Hierarchically porous graphitic carbon nitride: large-scale facile synthesis and its application toward photocatalytic dye degradation

For the first time we develop a novel strategy toward large-scale facile synthesis of hierarchically porous graphitic carbon nitride (hp-g-CN) by polymerization of melamine monomers using ammonium persulfate as an oxidant, followed by paralyzing the resulting microstructures under Ar. Then we use it as an efficient photocatalyst toward degradation of methyl orange dye under visible light irradiation.
