摘要:
采用一种改性的Hummers方法制备氧化石墨，通过X射线衍射、激光显微拉曼光谱、X射线光电子能谱、傅立叶红外等技术对催化剂的物化性质进行表征。结果显示，氧化石墨表面有丰富的含氧官能团。将氧化石墨用于碳酸乙烯酯和甲醇的酯交换反应，考察不同反应条件对碳酸乙烯酯转化率和碳酸二甲酯选择性的影响。氧化石墨表现出稳定且高的催化活性，在140〖KG3x〗℃，碳酸乙烯酯的转化率能达到73.6%。
Abstract:
Graphite oxide was prepared by modified Hummers method, and characterized by Xray diffraction, Raman spectra, Xray photoelectron spectroscopy, and infrared spectroscopy. It showed that graphite oxide had abundant oxygen functional groups on its surface. The catalytic performances of graphite oxide in the transesterification of ethylene carbonate and methanol were investigated, and the influences of different reaction conditions on the activity and selectivity to dimethyl carbonate were tested. The corresponding results indicated that graphite oxide exhibited high and stable catalytic activity, affording a maximum conversion up to 73% at 140〖KG3x〗℃.
