摘　　要：采用溶胶-凝胶法制备了半导体型金属氧化物ZrO2,并通过浸渍法将杂多酸H3PW12O40与其复合,获得了纳米复合光催化材料H3PW12O40/ZrO2,并在紫外光和可见光下考察了该复合材料对可溶性染料罗丹明B和亚甲基蓝的光催化活性。实验结果表明,该复合材料有较好的光催化活性。The solid material H3PW12O40/Ta2O5 was prepared by the sol -gel and wet impregnation method. The photoeatalytie properties of the as - synthesized composite were tested by the photocatalytie degradation of Rhodamoine B （RB） and Methylene Blue （MB） under UV and visible -light irradiation. The results showed that the composite exhibited higher photocatalytic activities.
