摘　　要：采用原位化学合成的方法合成了均匀掺杂的1,8,15,22-四苯氧基酞菁钴/二氧化钛(简称α-TP Co(Ⅱ)Pc/TiO_2)和1,8,15,22-四苯氧基酞菁铜/二氧化钛(简称α-TPCu(Ⅱ)Pc/TiO_2)复合材料。通过UV-Vis、XRD、TG进行了表征,并通过对罗丹明B的降解来考察材料的光催化性能。结果表明,α-TPMPc/TiO_2对罗丹明B降解具有较好的光催化活性,α-TPMPc敏化能有效地提高TiO_2的可见光光催化活性,且α-TPCo(Ⅱ)Pc/TiO_2的催化活性明显优于α-TPCu(Ⅱ)Pc/TiO_2。Titania-based 1,8, 15,22-tetra-phenoxy-cobalt phthalocyanine （namely a-TPCo （Ⅱ） Pc/TiO2 ） and 1,8,15,22-tetra-phenoxy-copper phthalocyanine （namely a-TPCu（ ]I ）Pc/TiO2） were synthesized suc- cessfully by the method of in-situ chemical synthesis. The samples were characterized by means of TG, XRD and UV-Vis. The photocatalytic activity was determined through the degradation of Rhodamine B （RhB）. The results showed that the photocatalytic activity of TiO2 could be improved effectively while a- TPMPc existed as the sensitizer, and a-TPCo（ Ⅱ ）Pc/TiO2 was more active than a-TPCu（ Ⅱ）Pc/TiO2.
