Abstract

MoS2-catalyzed coupled dehydrogenation and hydrodeoxygenation of lactic acid (LA) enables synergistic production of pyruvic acid and propionic acid. The activity in LA coupled reactions is dominated by phase structure, and 1T-MoS2 presents an excellent activity. Under optimal conditions, the LA conversion reached 72.5% together with 73% selectivity to pyruvic acid and propionic acid.
