| 摘 要： | 通过将聚苯乙烯与纳米氧化锌前驱体共混制备了复合材料前驱体,运用TG-DTA联机分析得到了其分解温度及相关热分解数据;前驱体经适当温度煅烧后得复合材料光催化剂,运用TEM、XRD、FT-IR、UV-Vis、ESR等测试手段进行了表征。在荧光灯作用下对复合材料光催化性能进行了检测,并与相同条件下纳米氧化锌的光催化性能进行了比对分析。结果表明,该复合材料在荧光作用下对甲基橙催化降解11h后,甲基橙的降解率为35%,与纳米氧化锌催化降解甲基橙5%的降解率相比有较大程度的提高。

| Abstract: | In this paper, complex precursor has been prepared by mixing polystyrene and nanometer ZnO precursor, and its decomposition temperature and relative thermal decomposition data were determined by the analysis of TG-DTA. The target complex was obtained by calcinating the precursor at appropriate temperature according to the results of TG-DTA analysis ; and it had been characterized using TEM ,XRD ,FF-IR, UV-Vis,ESR. Under the irradiation of fluorescence lamp, the photocatalytic property of this complex was tested and compared with that of pure nanometer ZnO. The results indicated that after irradiating 11 hours the decolorization proportion of methyl orange was 35% by using complex, which was much larger than 5% by using pure nanometer ZnO. |
