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。
The composite precursor was prepared by blending polystyrene and nano-ZnO precursor. The decomposition temperature and the related thermal decomposition data were obtained by TG-DTA analysis. The precursor photocatalyst was obtained by calcining the precursor at proper temperature, TEM, XRD, FT-IR, UV-Vis, ESR and other testing methods were used to characterize. The photocatalytic activity of the composites was tested under the action of fluorescent lamps. The photocatalytic properties of the composites were compared and analyzed under the same conditions. The results showed that the degradation rate of methyl orange was 35% after methyl orange was degraded catalytically under the action of fluorescence for about 11h, which was significantly lower than that of 5% degradation of methyl orange catalyzed by nano-ZnO improve.
