Cobalt phthalocyanine/SnO₂ nanocomposite was synthesized in-situ through the annulation of dicyanobenzene on the surface of SnO₂ nanoparticles with Co(Ⅱ) as template.The prepared products were characterized by means of XRD,DTA,UV-Vis and FT-IR methods.The photocatalytic activity of materials under visible light was also discussed.The experimental results indicate that Cobalt phthalocyanine and SnO₂ are indeed synthesized with the in-situ method.Under the visible light irradiation,CoPc molecules are excited first and then the excited electrons are injected into the conduction band of SnO₂ through the Co-O chemical bond.Superoxide radicals are formed by reaction with O₂,the degradative rate of Rodanming B is up to 87.1% within 150 min.The degradative rate is very stable during circulating degradation for 10 times.
