The Effect of Pentaerythritol in Synthesis of the Nanoporous Silica

Nanoporous silica with pore size in the rang of 2.5-3.5 nm was synthesized and characterized using BET surface measurement, SEM and XRD analysis. Pentaerythritol has been used as additive to change the morphology of MCM. The structural factors we focused on them, were MCM pore size, solidity and ordering. There was an optimum amount of alcohol in equal moles of Pentaerythritol and surfactant, toward observation the most sensible structural altering. At the other amounts, the aging times of samples could be changed to earn superlative qualifications. When the aging times were changed, an optimum aging time at 2 day was observed as well.
