We report the applicability of ZrO/ZnO impregnated onto a variety of MgO:SiO materials as heterogeneous catalysts for the conversion of ethanol to 1,3-butadiene. The selectivity to 1,3-butadiene is affected by the ratio of the basic MgO to the acidic SiO, with higher selectivities being observed as the mole fraction of MgO increases. The catalysts have been characterised by SEM, XPS, pXRD, BET surface area measurements and Si solid-state NMR spectroscopy.
