摘　　要：以硝酸锆和硝酸锌为原料,尿素为助燃剂,采用微波闪速法合成纳米ZrO2/ZnO复合材料,研究了纳米ZrO2/ZnO复合材料分别对甲基橙和罗丹明B的光催化降解性能。结果表明,在紫外光条件下,纳米ZrO2/ZnO复合材料光催化降解甲基橙效果明显优于罗丹明B。Nanometer ZrO2/ZnO composite was prepared via the microwave induction of flash burning method, with Zr（ NO3 ）4 and Zn（ NO3 ）2 as raw material,urea as combustion improver. The photocatalytic activity of products for Rhodamine B and methyl orange was studied. The results showed that under UV ir- radiation, degradation efficiency of methyl orange with nanometer ZrO2/ZnO composite was obviously higher than that of Rhodamine B.
