Mechanism of syngas conversion into C2-oxygenates such as ethanol catalysed on a SiO2-supported Rh–Ti catalyst
Abstract
13 C-Labelling studies on a Rh–Ti/SiO2 catalyst using 13CO and 13CH3OH revealed that in a CO–H2 reaction C2-oxygenates such as ethanol are formed from a common precursor e.g. acyl, being formed by CO insertion onto surface CH3/CH2 moieties derived from CO dissociation and the subsequent reaction of the carbon product with hydrogen.
