NOVELTY - Preparing iron phthalocyanine based material comprises (i) placing ordinary single-layer graphene in tube furnace, conveying ammonia gas for high-temperature heating to obtain nitrogen-doped graphene, (ii) placing nitrogen-doped graphene in tube furnace, introducing argon gas to carry out high-temperature heating to obtain defective graphene, (iii) choosing iron phthalocyanine, mixing with defective graphene, placing in ethanol and carrying out ultrasonic treatment and stirring process, and (iv) placing ultrasonically stirred sample in vacuum oven for drying, and then collecting out dried sample to obtain iron phthalocyanine/defective graphene composite. USE - The method is useful in preparing iron phthalocyanine based material for degrading bisphenol A by activating peroxymonosulfate (claimed). ADVANTAGE - The material: has high degradation rate and cycle stability, which can completely remove pollutants within 20 minutes, and exhibits excellent performance in effluent of actual sewage treatment plants; is environmentally friendly; and has excellent performance, which is very promising catalytic material.
