[0019] TiO 2 / Porous g-C 3 N 4 The preparation method of nanocomposite material, comprises the following steps:
[0020] Step A: Under stirring conditions, H 2 SO 4 The aqueous solution was added dropwise to the melamine aqueous solution to form a white suspension; the precipitate was obtained after stirring at 80°C for 2 hours; the precipitate was filtered, washed three times with distilled water and absolute ethanol, and dried at 60°C for 24 hours to obtain melamine sulfate; put into a corundum boat, followed by sintering in a tube furnace; after cooling to room temperature, the obtained yellow polymer product was ground a little to powdery particles to obtain g-C 3 N 4 particles;
[0021] Among them, H 2 SO 4 The molar concentration of aqueous solution is 0.02mol / L~2mol / L, the molar concentration of melamine aqueous solution is 0.02mol / L~2mol / L, the amount of control reactant makes H 2 SO 4 The molar ratio to melamine is 5:1~0.5:1; the protective atmosphere for s...
