主　　题：coal measure kaolin mesoporous materials hydrothermal synthesis 

摘      要：Mesoporous materials with the highest surface area were synthesized by hydrothermal treatment from coal-measure kaolin using cetyltrimethylammonium bromide（CTAB）as *** effect of several factors on surface area of products also had been *** products were characterized by FT- IR,HRTEM and N 2 adsorption and desorption isotherm plot *** was typical structure as Si-O,Si- OH and Si-O-Si of mesoporous materials in the framework of synthesized materials;the pore size distributions of the products showed a sharp peak at 3.82 *** effect of hydrothermal treatment time and the amount of template on the specific surface area of mesoporous materials was important,when the Surf/Si=0.135,and hydrothermal time=12 h,and the surface area of the product reached up to 1 070 m2/g,which was higher than other products.
