| 摘 要： | 通过一步水热法制备了Cu-石墨烯（Cu-RGO）催化剂，实现了Cu纳米颗粒的可控生长和氧化石墨烯（GO）还原的同步进行，并将所制备的Cu-RGO用于亚甲基蓝（MB）的催化降解研究。在H2O2存在条件下，当GO与Cu的质量比为3：17时，经过4h催化反应，Cu-RGO催化剂对亚甲基蓝的降解率可达到99.5%，经过6次循环使用对亚甲基蓝的降解率仍保持在98.1%以上，Cu-RGO催化剂展现了较高的催化活性及良好的稳定性。

| Abstract: | Afacile approach to prepare Cu-reduced graphene oxide (Cu-RGO) catalyst was developed via a one-step hydrothermal process. The suggested method enables simultaneously the deposition of Cu nanoparticles on RGO surfaces and reduction of graphene oxide. The degradation of methylene blue aqueous solution catalyzed by Cu-RGO was investigated. The results indicated that, in the presence of H2O2, the Cu-RGO catalyst with graphene oxide/Cu mass ratio of 3:17 showed the highest degradation rate of 99.5% in 4 h. Adegradation rate of 98.1% can be maintained after reusing for six times, showing high catalytic activity and excellent stability. |
