采用改进的溶胶凝胶法合成出二氧化钛(TiO_2)-活性炭(AC)协同吸附-光催化复合材料。采用XRD、FT-IR、TEM以及DRS等对所制备复合材料的晶相结构、表面结构等进行了表征。测试结果显示,AC的加入影响了TiO_2的粒径分布和粒径的大小。通过对水中污染物罗丹明B的降解来测试复合材料的光催化性能。测试结果显示,适量AC可以有效地提高材料的光催化性能。
Titania - activated carbon (AC) synergistic adsorption - photocatalytic composite was synthesized by the improved sol - gel method. XRD, FT-IR, TEM and DRS were used to characterize the crystal structure, surface structure and so on of the prepared composites. The test results show that the addition of AC affects the particle size distribution and particle size of TiO_2. The photocatalytic activity of the composites was tested by the degradation of rhodamine B in water. The test results show that the appropriate amount of AC can effectively improve the photocatalytic properties of the material.
