| Summary: | Transition metal oxides have been proposed for hydrogen storage. Samples were prepared by a post template method and hydrothermal treatment. TIk morphology of the samples was investigated by BET method and by Scanning filcclron Microscopy .The composition and crystal structure was examined by X-ray Powder Diffraction and Energy Disperse X-ray analysis. In order to obtain comparable results, commercial powders were tested by the same manner. By comparing results obtained for metal oxides before and after deposition it was found that presence of Pt and Pt increased amount of gas stored by -60% (the results were corrected by amount of hydrogen chemisorbed by Pt or Pd). It was concluded thai spillover effect is responsible for additional hydrogen adsorption. |
