Abstract Ammonium phosphates can be exploited as promising hydrogen storage materials. Hydrogen is produced due to hydrolysis of these compounds to produce nitrous, nitric and phosphoric acids. Hydrogen can be evolved from the proposed materials by only hydrolysis, the very low price, availability and easy preparation compared to most of the reported hydrogen storage materials. The doping process for titanium oxide with different percentage of metal develop the activity of the catalyst and increase the amount of hydrogen release from ammonium phosphate. Change the morphology of catalyst increase the capability of hydrogen release from ammonium phosphate. TiO2 nanofibers doped by Ag, Zn and Cd up to 1.5 wt% content from each dopant (can be produced with good morphology using the electrospinning), TiO2 nanofibers doped by Ag, Zn and Cd is a better than TiO2 nanoparticless doped by Ag, Zn and Cd. CNTs can be synthesis by CVD process and produced in a good morphology, TiO2/CNTs improve the rate of hydrogen release from ammonium phosphate. |
