Catalytic conversion of syngas to higher alcohols over mesoporous perovskite catalysts

Two types of mesoporous perovskite-type oxides (Meso-PTOs) were synthesized by combining a templated synthesis and a citrate complex method. The Meso-PTO catalysts exhibited superior catalytic activity in the higher alcohols synthesis from syngas compared to the bulk-PTO, likely due to the increased dispersion of active sites on the high surface of the Meso-PTOs. Moreover, the Meso-PTOs show higher productivity for C-3 and C-4 alcohols as well as C2+ oxygenates. Among the two Meso-PTOs developed here, the mesoporous LaFe0.7Cu0.3O3 catalyst was capable of significant suppression of the methanation reaction and better selectivity to higher alcohols compared to the mesoporous LaCo0.7Cu0.3O3 catalyst.
