| 摘 要： | 以十六烷基三甲基溴化铵(CTAB)为保护剂, 采用水热法成功制备了CuO纳米片. 将制备的CuO纳米片在H2O2存在下用于催化氧化降解亚甲基蓝, 探讨了其在不同反应条件(如温度、氧化剂浓度及催化剂用量)下对亚甲基蓝降解反应的影响. 该催化反应符合一级动力学模型, 活化能为54.0kJ/mol. CuO纳米片表现出非常高的催化活性, 但其稳定性与重复利用性有待于进一步提高. |

| Abstract: | Cupric oxide (CuO) nanosheets were prepared by the hydrothermal method with the use of cetyltrimethylammonium bromide (CTAB) and were used as the catalyst for the oxidation degradation of methylene blue with H2O2. The effects of temperature, oxidant concentration, and catalyst dosage were evaluated. The catalytic reaction obeyed first order kinetics, and the activation energy was 54 kJ/mol. Although the CuO nanosheets show high activity, their stability and reusability still need improvement. |
| Keywords: | Cupric oxide Nanosheet Methylene blue Oxidation degradation |
