纳米材料ZrO_2微波增强光催化降解染料

Microwave enhanced photocatalytic degradation dyes by nanomaterial ZrO_2

采用溶胶-凝胶再结合程序升温溶剂热法低温制备了晶型结构良好、孔径分布较均匀且比表面积为130.4 m2/g的纳米光催化材料ZrO2。在微波无极灯照射下,以光催化降解染料为反应体系,研究了该纳米材料微波增强光催化性能。实验结果表明,在微波作用下,ZrO2的光催化活性显著增强。

The nano-material ZrO2 was prepared by a Single-step Sol-gel-hydrothermal method, of which the average pore diameter was nanoporous structures, and that of large surface area was 130.4 m^2/g.The photoeatalytie properties of the as-synthesized material were tested by the photoeatalytie degradation of dyes under UV and microwave irradiation. The results showed that ZrO2 exhibited higher microwave enhanced photoeatalytic activities.
