摘要
采用化学氧化法制得K_8[CuW_(11)CdO_(40)]/PANI掺杂材料,并用IR、UV、XRD、EDS、SEM对所合成的掺杂材料进行了表征。并利用所合成K_8[CuW_(11)CdO_(40)]/PANI掺杂材料为催化剂,研究了对亚甲基蓝溶液光降解催化活性。通过实验确定了光降解的最佳条件为:亚甲基蓝溶液初始pH为2,亚甲基蓝溶液初始浓度为10mg·L^(-1),催化剂用量为0.08 g,在光照100 min,亚甲基蓝溶液的脱色率为98.11%。因此,K_8[CuW_(11)CdO_(40)]/PANI掺杂材料是一种很好的光降解催化剂。
The doping materials of K 8 [CuW11 CdO40 ]/PANI were prepared by the chemical oxidation method ,and were character-ized by UV、IR、XRD、SEM、EDM.The photocatalytic degration acitity of methylene blue solution was studied by doping materials catalyst.The experment results indicated that the most suitable conditions of photocatalytic degradation were that the initial pH of methylene blue solution was 2,the initial concentration of methylene blue solution was 10 mg？L-1,the catalyst quantity were 0.08g, within 110 min the decolorizing efficiency of the methylene blue solution was 98.11%.so K 8[CuW 11CdO 40]/PANI was the good photocatalytic degration catalyst.
