Abstract

At high loading, methanol reacts under ambient conditions with acidic hydroxyls of H-ZSM-5 to methoxylate framework oxygen; while a significant proportion remains hydrogen bonded to the framework with a protonated geometry. The findings not only explain the data which have been published so far, but also pave a way forward for potential unravelling of the initial reaction steps in the relevant chemical processes.
