Acidity as Descriptor for Methanol Desorption in B-, Ga- and Ti-MFI Zeotypes

The isomorphous substitution of Si with metals other than Al in zeotype frameworks allows for tuning the acidity and, therefore, to tailor catalyst’s properties as a function desired catalytic reaction. In this study, B, Ga, and Ti are incorporated MFI framework silicalite samples following series increasing is observed: Ti-silicalite < B-silicalite Ga-silicalite. It also observed that lower sample, easier methanol desorption from surface. target reaction, namely direct conversion methane methanol, extraction affected by acidity. Therefore, results shown study contribute more enriched knowledge
