Özet

In this study, TiO₂-supported Ni-Mo-Ru–B (TiO₂@Ni-Mo-Ru–B) catalyst was synthesized by chemical reduction method for hydrogen production from the hydrolysis of potassium borohydride (KBH₄) solution. The characterizations of the synthesized catalysts were carried out with BET, XRD, and SEM. In hydrolysis experiments, the effects of parameters such as KOH concentration, KBH₄ concentration, catalyst amount, metal/TiO₂ ratio, and temperature on hydrogen production rate were investigated. The optimum metal/TiO₂ ratio was determined as 10% and the hydrogen production rate of the catalyst at 30 °C was calculated as 2410.28 mL/min.g_cat. In addition, the reaction rate order was found to be 0.8 (nth order); accordingly, the value of the activation energy was obtained from the Arrhenius equation as 51.807 kJ/mol.
