Single-pass transformation of syngas into ethanol with high selectivity by triple tandem catalysis.

ABSTRACT: Synthesis of ethanol from non-petroleum carbon resources via syngas (a mixture of H₂ and CO) is an important but challenging research target. The current conversion of syngas to ethanol suffers from low selectivity or multiple processes with high energy consumption. Here, we report a high-selective conversion of syngas into ethanol by a triple tandem catalysis. An efficient trifunctional tandem system composed of potassium-modified ZnO-ZrO₂, modified zeolite mordenite and Pt-Sn/SiC working compatibly in syngas stream in one reactor can afford ethanol with a selectivity of 90%. We demonstrate that the K⁺-ZnO-ZrO₂ catalyses syngas conversion to methanol and the mordenite with eight-membered ring channels functions for methanol carbonylation to acet
