摘要： 通过使用氨气作氮源,氮化介孔氧化硅和含铝氧化硅(SBA-15和Al-MCM-41)的前驱体(含模板剂),成功制备出高氮含量的有序氮氧化物介孔材料。主要氮化条件为:1273～1323K,8～24h.采用 CNH元素分析、红外光谱、Si固体核磁共振谱(MASNMR)、N2吸附-脱附分析、小角XRD和高分辨透射电镜(HRTEM)进行表征,分析结果表明经过高温长时间氮化制备出的高氮含量(～21wt％)的氮氧化硅和含铝氮氧化硅介孔材料仍然具有高达700～900m2g-1的比表面积、窄的孔径分布和良好的有序性.

Abstract: The ordered oxynitrides mesoporous materials were successfully prepared by the ni- tridation of Al-MCM-41 and SBA-15 mesoporous materials (containing template) in flowing NH3 environment. The composition and structure of the synthesized materials were analyzed by CNH analysis, IR spectrum, Si MAS NMR, N_2 sorption, low-angle XRD, and HRTEM. The results of analysis show that the obtained oxnitrides mesoporous materials by nitriding at higher tempera- ture (1273～1323K) and long soaking time (8～24h) still possess good order, high nitrogen content (10～21wt%), high surface area (700～900m2g-1), and narrow pore distribution.

Key words: oxynitrides, orderd mesoporous materials, Al-MCM-41, SBA-15
