中文摘要：
采用[Ru（dpp）3][（4-Clph）4B]2作为光活性染料,制备出了染料敏化TiO2/石墨烯复合材料,并以有机染料甲基橙的降解为模型评价其光催化活性。结果表明：当TiO2与石墨烯质量比为1.12,负载0.25 mg[Ru（dpp）3][（4-Clph）4B]2时复合材料光降解效果最佳,可见光辐射80 min后降解率达到96.5%。
英文摘要：
[Ru（dpp）3][（4-Clph）4B]2-sensitized TiO2/graphene nanocomposites were successfully prepared and its visible-light photocatalytic properties were evaluated by the photodegradation of organic dye methyl orange under full sunlight illumination. The results revealed that when 0.25 mg [Ru（dpp）3][（4-Clph）4B]2were used to sensitized TiO2/graphene nanocomposites（the mass ratio of TiO2：graphene, 1.12）, decolourizing rate of 10 mg/L methyl orange can rise up to 96.5% after 80 min irradiation.
