摘　　要：本文通过高温固相反应制备出KCa2Nb3O10,所制备的样品通过质子交换制备出HCa2Nb3O10,用C6H13NH2对样品进行柱撑制备出HCa2Nb3O10/n-C6H13NH2,然后将Ni2+插入HCa2Nb3O10层间区域,最后通过硫化反应制备出插层复合材料HCa2Nb3O10/NiS。在40W紫外灯照射下,研究了各光催化剂分别降解甲基橙和亚甲基蓝溶液的光催化活性,实验结果表明复合后的催化剂HCa2Nb3O10/NiS光催化分解甲基橙和亚甲基蓝的活性均高于未复合的催化剂单体。HCa2Nb2O10can be prepared by high temperature solid state reaction, HCa2Nb2O10 was prepared by proton exchange, HCa2Nb2O10 is pillared with , then put Pb2＋ and Cd2＋ into the HCa2Nb2O10 interlayer region, finally HCa2Nb2O10/NiS is prepared by vulcanization reaction. The synthetic samples are used as photocatalysts to promote the degradation of methyl orange and methylene blue solution under 40WIN light irradiation for 4 hours. Research shows that photocatalytic decomposition of methylene blue and methyl orange activity with HCa^Nb^O~dNiS were higher than that with monomer.
