CoPc（β-OC6Cl5）4/SnO2复合材料的制备及光催化性能研究

用原位合成的方法制备不同物质的量配比的CoPc(β-OC6Cl5)4/SnO2复合材料,利用UV,IR和XRD对产物进行表征,并在可见光条件下测定其对罗丹明B光催化降解反应产率.结果表明:复合材料在紫外光谱中出现红移现象,红外光谱中出现了M—O的振动吸收峰,XRD谱图中显现出SnO2晶粒变小,说明CoPc(β-OC6Cl5)4与SnO2之间形成部分化学键,负载量物质的量分数为4%的CoPc(β-OC6Cl54)/SnO2复合材料对罗丹明B的光催化降解产率最高.

Synthesis and photocatalytic activity of β-tetra-pentachlorophenyloxy-cobalt phthalocyanine/SnO2 nanocomposite

β-tetra-pentachlorophenyloxy-Cobalt phthalocyanine/SnO2 nanocomposite with different mole proportion was synthesized by in-situ method.The prepared products were characterized by means of UV,IR and XRD methods.The photocatalytic activity of β-tetra-pentachlorophenyloxy-Cobalt Phthalocyanine/SnO2 nanocomposite was investigated by using photocatalytic degradation of Rodanming B in visible light as a model reaction.The experimental results indicate that the UV spectrum of four percent production brings about moving to more longer wavelength than others in its characteristic absorption Q belt;the vibration absorption peaks of M—O all appreared in IR spectrum,the size of crystal particals have become smaller than before,all that show in the complex β-tetra-pentachlorophenyloxy-Cobalt Phthalocyanine and SnO2 were linked with partial chemical bond.The degradatoin reaction yeild of four percent products for Rodanming B up ot 63.7% is higher than others.
