Title: Shedding light on the atomic-scale structure of amorphous silica–alumina and its Brønsted acid sites

Abstract

Advanced solid-state NMR methods, using dynamic nuclear polarization (DNP), are applied to probe the atomic-scale bulk structure of amorphous silica–alumina catalysts prepared by flame-spray pyrolysis, and the structure of their Brønsted acid sites.
