Glycerol steam reforming is one of the most studied routes to produce hydrogen from this oxygenated compound. Metal catalysts are by far the most investigated systems in this reaction. Choosing a suitable combination of metal and support is crucial to reach high conversion and catalyst stability. Layered double hydroxides (LDH) are able to produce mixed oxides by calcination. In this contribution, Pt catalysts supported on MgO-Al2O3 prepared from LDHs were studied in the steam reforming of glycerol. Synthesis methods were evaluated as regarding the catalytic performance, product distribution and catalyst stability. Keywords: glycerol, hydrogen, basic catalysts, LDH.
