以4,4’,6,6'-四叠氮基偶氮-1,3,5-三嗪为前体热解制备氮化碳纳米材料

摘要

4,4' , 6,6'-Tetra(azido)azo-l ,3 ,5-triazine(TAAT) was synthesized by an improved synthesis method with the yield of 82. 1%. DSC, IR,NMR, elemental analysis as well as crystal structure diffraction were used to characterize the TAAT and intermediate products. C2N3 and C3N5 whose N/C ratios highly resembled the theoretical peers were prepared by pyrolysis from TAAT. The mechanisms for TAAT pyrolysis and C2N3/C3N5 generation were discussed.%通过改进的合成方法制备4,4’,6,6'-四叠氮基偶氮-1,3,5-三嗪(TAAT),总产率为82.1％.采用DSC、IR、NMR、元素分析等对TAAT和中间产物进行了表征,并对其单晶结构进行了分析.以TAAT为前体,采用热解法制备出碳氮比非常接近理论值的C2 N3和C3 N5氮化碳纳米材料.推测出TAAT可能的热解过程及C2 N3、C3 N5氮化碳纳米材料的生成机理.
