Supports play a vital role in stable hydrogen production at high temperatures. Often mixed oxides are used as supports in a reforming process because they demonstrate the combined properties of the parent oxides.

In this talk, I would present the synthesis of TiO2 Al2O3 mixed oxide and their application as supports for hydrogen generation by propane partial oxidation. We observe that the presence of TiO2 improves the surface area of the Al2O3 upto 900C. An optimal loading of TiO2 is necessary to maximize Hydrogen generation. Furthermore, long-term propane partial oxidation (~30hrs) clearly shows that the presence of TiO2 results in improved hydrogen generation.
