摘　　要：采用原位合成的方法制备了CoPc/SnO2/TiO2复合材料,利用UV,IR,XRD,SEM对产物进行了表征.结果表明,复合材料在紫外光谱中出现了酞菁特征吸收Q带的红移现象,红外光谱中出现了M-O的振动吸收峰,在XRD图谱中显示出SnO2/TiO2晶粒变小,并且在SEM中看出晶粒尺寸基本和XRD图谱显示一致.说明CoPc与SnO2/TiO2之间形成部分化学键.Cobalt Phthalocyanine/SnO2/TiO2 nanocomposite are synthesized by in-situ process. The products are then characterized by means of UV, IR, XRD and SEM methods. The experimental results indicate that different degree of red shift on the Q band with maximum absorption of the substitute phthalocyanine occur, that the vibra-tion absorption peaks of M-O appear in IR spectrum, that the size of crystal particles becomes smaller than before in XRD spectrum and that the size of crystal particles perceived in SEM is the same as that in XRD spectrum. It is suggested that the complex of Cobalt Phthalocyanines and SnO2/TiO2 are linked with partial chemical bond.
