使用Cu（NO3）（2）、六亚甲基四胺和NaOH溶液在95 ℃下合成了纺锤形氧化铜（CuO）微粒。该细长CuO颗粒具有类似于杨桃的形状，其长度近似于1 μ m，宽度近似于300 nm。它们是由厚度约为5 nm的纳米片组成的。这种粒子可用于在类似于0.01 M H2O2的存在下光催化降解罗丹明B。在100 W卤钨灯照射下，CuO的光催化活性高于P25和市售CuO粉末。它们非常稳定，可以回收而不会有相当大的活性损失。其他染料和有机污染物，如甲基橙子、亚甲蓝、蚀红B。对硝基苯酚在相同条件下也能发生光降解。这些特性显示了CuO颗粒在环境修复中的实际应用。(C)2011 Elsevier B.V.保留所有权利。
Spindly cupric oxide (CuO) micro-particles were synthesized using Cu(NO3)(2), hexamethylenetetramine, and NaOH solutions at 95 degrees C. The spindly CuO particles had a shape similar to a carambola of similar to 1 mu m in length and 300 nm in width. They were composed of nanosheets with a thickness of similar to 5 nm. Such particles could be used in the photocatalytic degradation of rhodamine B in the presence of similar to 0.01 M H2O2. Under irradiation by a 100W halogen tungsten lamp, the CuO showed photocatalytic activities higher than those of P25 and commercially available CuO powder. They were very stable and could be recycled without considerable loss of activity. Other dye and organic pollutants such as methyl orange, methylene blue, erosin B. and p-nitrophenol could also be photodecomposed under identical conditions. These characteristics show the practical applications of the CuO particles in environmental remediation. (C) 2011 Elsevier B.V. All rights reserved.
