The catalytic data strongly suggest a consecutive reactions path involving the dehydration to acrolein over the zeolite acid sites followed by a selective reduction through a hydrogen-transfer reaction. Acidity is expected to play a major role in what concerns the selectivity, as demonstrated by the catalytic results obtained by the impregnation of vanadium on a previously Cs-exchanged sample that achieved ca. 30% selectivity to allyl alcohol at ca. 20% glycerol conversion.engAllyl alcoholVanadium oxideGlycerol conversionBeta zeoliteSustainable chemistryjournal articlehttps://doi.org/10.1016/j.catcom.2019.04.015
