Empowering Catalyst Supports: A New Concept for Catalyst Design Demonstrated in the Fischer–Tropsch Synthesis

The Fischer–Tropsch (FT) synthesis is traditionally associated with fossil fuel consumption, but recently this technology has emerged as a keystone that enables the conversion of captured CO2 sustainable hydrogen to energy-dense fuels and chemicals for sectors which are challenging be electrified. Iron-based FT catalysts promoted alkali transition metals improve reducibility, activity, selectivity. Due their low concentration metastable state under reaction conditions, exact speciation location these promoters remain poorly understood. We now show selectivity such potassium manganese, locked into an oxidic matrix doubling catalyst support, surpass conventional promoting effects. La1–xKxAl1–yMnyO3−δ (x = 0 or 0.1; y 0, 0.2, 0.6, 1) perovskite supports yield 60% increase in CO comparable promotion reduced overall C1 presented approach seems decouple enhancement water–gas shift reaction. introduce general design principle can extended other key catalytic processes relying on metal promotion.
