Abstract

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
