The direct synthesis of templated super-microporous silica with spherical and cylindrical shapes was achieved in a water/acetonitrile/n-dodecylamine system
using 3-mercaptopropyltrimethoxysilane and 3-trifluoromethyltrimethylsilane as co-template.The benefits of this system to prepare such silicas were high surface area
much enhanced wall thickness
and consequently to greater structural stability.The particles obtained from this route were spherical and cylindrical.The sample was characterized by using N2 adsorption /desorption
XRD
FTIR
SEM
TG-DSC and 13C CP MAS NMR methods,and the process of the direct preparation was given.
