•Zn-spinel oxides are catalytically active in the SRE process.•The zinc cobaltate is the most active SRE catalyst among studied spinels.•The presence of zinc in the structure Zn–Co facilitates the reduction of cobalt.•H2 yield increases in the order: ZnAl2O4 < ZnFe2O4 < ZnCo2O4.
Hydrogen production by ethanol steam reforming (SRE) was studied on zinc based catalysts with spinel-like structure. ZnM2O4 (M = Al, Co, Fe) mixed oxides were prepared by sol–gel technique with citric acid and characterized by XRD, TPR-H2, SBET, TPD-NH3 and decomposition of cyclohexanol. The XRD patterns confirm presence of well defined spinel-like structure of prepared materials. The highest catalytic activity towards hydrogen production was found for zinc cobaltate: the hydrogen yield on this catalyst is 2.8 mol H2/mol EtOH. The ZnO promoting the reduction of cobalt cations to Co0 that is more active in SRE.
