Highly active and selective binary MgO–SiO₂ catalysts for the production of 1,3-butadiene from ethanol

Abstract

Wet-kneaded binary MgO–SiO₂ composite catalysts gave exceptionally high productivity of butadiene governed by a subtle balance of acid–base sites in relation to the formation of an interfacial Si–O–Mg linkage and by varying preparation methods and MgO to SiO₂ ratios.
