We report the preparation by a simple one-pot wet process of nanocomposites of different loading of manganese oxide supported on partially reduced graphene oxide (MnO₂/pRGO). The nanocomposites showed excellent catalytic activity for the one-step amination of benzene. The 5 wt% MnO₂/pRGO catalyst showed good efficiency towards benzene conversion (77%) with 100% selectivity towards aniline under mild reaction conditions for 90 min at 70 °C. From the recycle experiments, a 12% decrease in conversion after the 4th run was found. The new catalytic materials were characterised by XRD, HRTEM, SEM, Raman techniques and N₂ physical adsorption measurements.

我们报告了通过简单的一锅湿法制备负载在部分还原氧化石墨烯 (MnO ₂ /pRGO)上的不同负载量的氧化锰的纳米复合材料。该纳米复合材料对苯的一步胺化表现出优异的催化活性。5 wt% MnO ₂ /pRGO 催化剂显示出良好的苯转化效率（77%），在温和的反应条件下，在 70 °C 下反应 90 分钟，对苯胺的选择性为 100%。从循环实验中，发现第 4 次运行后转化率降低了 12%。通过XRD、HRTEM、SEM、拉曼技术和N ₂物理吸附测量对新型催化材料进行了表征。
