Mesoporous Structure Control of Silica in Room-Temperature Synthesis under Basic Conditions

Figure 10

Effects of NH₃ molar ratio on formation of silica mesostructure: the molar composition of the reaction mixture was fixed as follows: TEOS : NH₃ : EtOH : CTABr : H₂O = 1 :  : 40 : 0.2 : 400; the NH₃ molar ratio was (a) , (b) , and (c) .
