The facet-regulated oxidative dehydrogenation of lactic acid to pyruvic acid on α-Fe2O3†
Abstract
We propose a highly active α-Fe2O3 catalyst for the oxidative dehydrogenation of lactic acid to value-added pyruvic acid in air. The activity is determined by the utilized crystal face, due to the different adsorption energies of lactic acid molecules on different exposed planes. Furthermore, Fe sites show more preferential adsorption than crystal O sites.
