| 摘 要： | 以乙酸铜为铜源,β-环糊精为表面活性剂,NaOH为添加剂,KBH4为还原剂,在室温水溶液中制备了直径约为50 nm的Cu2O,对产物的组成、能隙、光催化性能进行了分析。研究表明:产物结晶性良好,粒径分布较均匀,且产率高;此外,该纳米Cu2O由于比表面积大,对甲基橙在30 min内的催化效率高达94.9%,甲基橙几乎全部被降解,显示出良好的催化活性。

| Abstract: | With copper acetate as copper source, beta cyclodextrin as surfactant, NaOH as additive and KBH4 as reducing agent, the cuprous oxide nanoparticles with a diameter of about 50 nm were prepared in aqueous solution at room temperature. The composition, energy gap and photocatalytic performance of the products were analyzed. The study showed that the products had uniform particle size distribution, good crystallinity and high yield. As the as-prepared Cu2O nanoparticles had a larger surface area, the catalytic efficiency on methyl orange was about 94 . 9 % in 30 min, almost all methyl orange was degradated, showing that the product had a good photocatalytic activity. |
