The main objective of this work was to investigate the different effects of transition metals (TiO 2 , VCl 3 , HfCl 4 ) on the hydrogen desorption/absorption of NaAlH 4 . The HfCl 4 doped NaAlH 4 showed the lowest temperature of the first desorption at 85°C, while the one doped with VCl 3 or TiO 2 desorbed at 135°C and 155°C, respectively...
Thin film Pt/TiO 2 catalysts are evaluated in a polymer electrolyte electrochemical cell. Individual thin films of Pt and TiO 2 , and bilayers of them, were deposited directly on Nafion membranes by thermal evaporation with varying deposition order and thickness (Pt loadings of 3–6μgcm −2 ). Structural and chemical characterization was performed by transmission electron microscopy...
