N2 - Glycerol is an attractive biomass-derived oxygenate, given its ready availability and strong potential to become a primary building block in future biorefinery schemes. Glycerol can be converted into hydrogen by the aqueous phase reforming (APR) process. The production of hydrogen by APR over supported metal catalysts comes with significant challenges with regards to selectivity. Hydrogen selectivity plays a role of utmost importance in catalyst development for APR of oxygenated hydrocarbons. Here, we report a new, highly efficient Pt-Cu/Mg(Al)O catalyst system for the APR of glycerol. The varying combinations of platinum and copper on basic magnesium-aluminium mixed oxide supports show high hydrogen selectivity as the formation of undesired alkanes, such as methane, is significantly suppressed. Extensive characterization of the catalyst system has been done by various techniques, including N 2 physisorption, XRD, TEM and EXAFS analysis. The new catalyst outperforms the benchmark Pt/Al2O 3 catalyst in hydrogen selectivity and limited formation of alkanes.
