Ruthenium and Platinum-Modified Titanium Dioxide Support for NaBH₄ Hydrolysis.

ABSTRACT: Highly stable platinum (Pt) and ruthenium (Ru)-based catalysts on titanium oxide (TiO₂) nanoparticle support were prepared. The productivity of hydrogen generation from sodium borohydride (NaBH₄) hydrolysis was observed to be as high as 95%. The activation energies for the hydrolysis reaction in the presence of Ru/TiO₂ in aqueous and alkaline solutions were 62.00 and 64.65 kJ mol^-1, respectively. On the other hand, the activation energy value of the hydrolysis reaction with the Pt/TiO₂ catalyst decreased from 60.5 to 53.2 kJ mol^-1, and the solution was changed from an aqueous to an alkaline medium. The experimental results have indicated that NaOH concentration (ranging from 0.5 to 2 M) affected the hydrogen generation rate
