摘　　要：采用化学修饰法制备不同摩尔配比的酞菁镍、SnO2(NiPc-SnO2)纳米复合材料。对制备的复合粒子进行XRD和IR表征,测定其在可见光条件下对罗丹明B的光催化降解能力。结果表明,酞菁镍-SnO2纳米复合材料红外光谱图中出现了M-O的振动吸收峰,表明NiPc与SnO2之间形成了部分化学键。在室温和可见光条件下,摩尔配比为1∶50的NiPc-SnO2纳米复合材料对罗丹明B的光催化降解率是64.3%。SnO2经NiPc敏化之后,在可见光范围内具有显著的光催化性能。Nickel phthalocyanine-SnO2 （NiPc-SnO2） with different mole proportionwas synthesized by chemical modification method. The products were characterized by means of XRD and IR methods. The photocatalytic activity of NiPc-SnO2 nanocomposite was investigated by using photo catalytic degradation of Rodanming B in visible light as a model reaction. The vibration absorption peaks of M-O appeared in IR spectrum, showing that in the complex NiPc and SnO2 were linked with partial chemical bond. Under visible light irradiation, the degradation rate of Rodahming B is up to 64. 3% when using NiPc-SnO2 nanocomposite of mole proportion 1：50 as catalyst at room temperature. NiPc-SnO2 nanocomposite has remarkable photocatalytic activity under visible light irradiation.
