Edge-rich molybdenum disulfide tailors carbon-chain growth for selective hydrogenation of carbon monoxide to higher alcohols.

ABSTRACT: Selective hydrogenation of carbon monoxide (CO) to higher alcohols (C₂₊OH) is a promising non-petroleum route for producing high-value chemicals, in which precise regulations of both C-O cleavage and C-C coupling are highly essential but remain great challenges. Herein, we report that highly selective CO hydrogenation to C_2-4OH is achieved over a potassium-modified edge-rich molybdenum disulfide (MoS₂) catalyst, which delivers a high CO conversion of 17% with a superior C_2-4OH selectivity of 45.2% in hydrogenated products at 240 °C and 50 bar, outperforming previously reported non-noble metal-based catalysts under similar conditions. By regulating the relative abundance of edge to basal plane, C_2-4OH to methanol selectivity ratio can b
