The invention discloses a preparation method of carbon nitride compound with high catalytic degradation activity and belongs to the technical field of photocatalyst preparation. According to the preparation method disclosed by the invention, tripolycyanamide, zinc nitrate hexahydrate and 2-methylimidazole are utilized as raw materials, and ZIF-8/g-C3N4 compound can be finally obtained through calcining and solvent heat treatment. Adsorption capacity of the synthesized ZIF-8/g-C3N4 compound to organic pollutants is enhanced; meanwhile, service life of electron-hole pairs is prolonged, transferof photo-induced electrons is promoted, catalytic degradation activity to the organic pollutants is higher under the simulated sunlight, a degradation rate is 3.03 times of that of original g-C3N4, and higher practical application value is achieved.
