用两步水热法合成了BiOCl-RGO复合材料。先在乙二醇和去离子水的混合溶液中合成直径约为400 nm、由纳米片构成的微球状单一BiOCl样品,在此基础上引入RGO载体制备出BiOCl-RGO纳米复合材料。使用 Raman光谱、XRD、XPS等手段表征样品的物相构成,用SEM和TEM观测其微观形貌,通过降解甲基橙评定样品的光催化性能。结果表明,水热温度显著影响复合材料的光催化性能,在140℃制备的BiOCl和石墨烯结合的样品具有最高的光催化性能。 |

Composites of BiOCl-RGO were synthesized via a two-step hydrothermal method. Firstly plain BiOCl was synthesized in the mixed solution of ethylene glycol and deionized water, the acquired nanosphere-like BiOCl of about 400 nm in diameter composed of many nanosheets. Then the RGO carrier was deposited onto the plain BiOCl to prepare BiOCl-RGO nanocomposites. The composites were characterized by Raman spectroscopy, XRD, XPS, SEM and TEM. The photocatalytic property of the composites was evaluated by degrading methyl orange. The results show that the temperature of hydrothermal process significantly affects the photocatalytic property of the composites. The composite of BiOCl -graphene prepared at 140°C shows the highest photocatalytic performance. |
