Abstract:	摘要： Dye-sensitized TiO sub(2)/SBA-15 was prepared using a two-step route, including grafting a thin layer of TiO sub(2) onto SBA-15 and then impregnating it with 2,9-dichloro quinacridone (DCQ) molecules. The prepared material was characterized by X-ray diffraction (XRD), High-resolution transmission electron microscopy, atomic absorption spectroscopy, nitrogen sorption isotherm, Thermal gravimetric analyses, UV-Vis. The XRD patterns of SBA-15 and TiO sub(2)/SBA-15 exhibit a peek of (100), which is the characteristic of a highly ordered hexagonal structure. UV-Vis spectrum of TiO sub(2)/SBA-15 shows the band edge of 400 nm. After functionalized by DCQ, a new band between 500 and 600 nm emerges, which enables the catalyst to absorb visible light. For photocatalytic reduction of CO sub(2) into methanol in water under 100 W halide lamp illumination, DCQ-TiO sub(2)/SBA-15 exhibits superior methanol yield (0.44 mu mol g super(-1)-cat h super(-1)) than that (0.16 mu mol g super(-1)-cat h super(-1)) of DCQ-P25 TiO sub(2 出版日期： 2012-05-01 出處： Journal of environmental engineering and management, 2012-05, Vol.22 (3), p.167-172 識別號： ISSN: 1022-7636 識別號： EISSN: 1022-7636
