The chief benefits of post-synthetic silylation are simplicity and versatility, given the wide variety of commercially available silylation agents. RSi(OEt)3 and RSiCl3 are the most commonly used as silylating agents. Silylated materials possess lower BET surface areas and pore volume.
Even though many experimental have been done in the silylation of MCM-41, there is no report confirming the effect on any surface properties of the silylation of M41S from rice husk silica. This study is a continuous work on surface modification of RH-MCM-41 with the objective to improve its hydrophobicity. The influence of several parameters such as the type and concentration of silylating agents, and reaction time were investigated. N2 adsorption, XRD, FTIR, and the
adsorptions of a water–toluene mixture through breakthrough curves were employed to analyze sample materials
