Three different precursors(melamine,cyanoguanidine and urea)and different atmosphere affected g-C3N4 prepared by high temperature thermal polymerization,g-C3N4 was prepared by liquid phase stripping.Through X-ray diffraction analysis of g-C3N4 (XRD)and FT-IR,structure difference of g-C3 N prepared with different raw materials,and the advantages and disadvantages of crystallization of g-C3N4 prepared in different atmosphere were analyzed.The study considers the crystallization properties,interplanar spacing and external conditions,selects melamine as precursors,and conducts conducts liquid stripping treatment of g-C3N4 prepared in air atmosphere.By SEM image characterization,the longer the crushing time of g-C3N4 cells is,the smaller the particle size is.The results show that the influence of raw material on the preparation of nano carbon nitride is mainly manifested in the crystalline property and crystal surface spacing,and the diameter of g-C3N4 in the preparation of nano nitride carbon changes.
