摘要：
The mesoporous silica molecular sieves, MCM-41, were synthesized under acid condition, and their pore sizes were regulated by adding 1,3,5-trimethylbenzene (TMB) as organic assistant agent in the reactant mixture. The characteristics of samples were investigated using XRD, IR and N2 adsorption techniques. It shows that the pore sizes, ordered degree and BET surface of the sample can be increased effectively with the addition of TMB if its content in mole fraction is below than 0.4, but its ordered degree will decrease when it exceeds the value. In addition, the effect of assistant agent on mesoporous structure is discussed.
