Abstract
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 C 2+ oxygenates. Among the two Meso-PTOs developed here, the mesoporous LaFe 0.7Cu 0.3O 3 catalyst was capable of significant suppression of the methanation reaction and better selectivity to higher alcohols compared to the mesoporous LaCo 0.7Cu 0.3O 3 catalyst.
