摘要
采用浸渍和喷涂法制备了TiO2/ACF、CNTs/TiO2/ACF和Graphene/TiO2/ACF光催化复合材料。以甲醛为目标化合物在光催化反应器中,254nm紫外灯作光源,光强20W,甲醛初始浓度2.41mg.L-1条件下,研究了甲醛在TiO2/ACF、CNTs/TiO2/ACF和Graphene/TiO2/ACF光催化复合材料上的吸附-光催化净化行为。初步结果表明复合光催化剂活性高低顺序为:Graphene/TiO2/ACF>CNTs/TiO2/ACF>TiO2/ACF。
The immersion and spray coating methods were used to prepared TiOJACF, CNTs/TiOJACF and graphene/TiOJACF photoeatalytie eomposite materials, The behaviors of adsorption-photocatalytie purifieation of formaldehyde on TiOJACF, CNTs/TiOJACF and grapheme/TiOJACF photoeatalytie composite materials were studied in the photoeatalytie reactor under the eonditions of that the wavelength of UV irradiation was 254nm, the irradiation intensity is 20W and the initial eoneentration of the formaldehyde was 2.4ling ·L^-1. The preliminary results showed that the aetivity order of photocatalytie composite material was as follows： graphene/TiO2/ACF〉CNTs/TiO2/ACF〉TiO2/ACF.
