NOVELTY - Producing non-metallic photocatalyst comprises forming a carbon polymer solution including a carbon polymer material; adding carbon nitride to the carbon polymer solution; adding alpha -sulfur to the carbon polymer solution; and forming a carbon nitride-carbon polymer material- alpha sulfur composite in which the carbon nitride, alpha -sulfur, and the carbon polymer material are bound, where the component ratio of the carbon nitride, the carbon polymer material, and alpha -sulfur is set according to the mass ratio to a first ratio, a second ratio, and a third ratio, and the size and number of pores of the carbon nitride-carbon polymer material- alpha -sulfur composite are changed according to the first ratio, the second ratio, and the third ratio, and the surface area is increased by using the pore control, and the energy band gap of the carbon nitride-carbon polymer material- alpha -sulfur composite was adjusted according to first ratio, second ratio, and third ratio. USE - The method is useful for producing non-metallic photocatalyst. ADVANTAGE - The non-metallic photocatalyst generates hydroxy radicals based on a solution process rather than hydrothermal synthesis, having carbon polymer material has an effect of controlling the reactivity of the photocatalyst by controlling the composition ratio, and has high reactivity.
