dc.description.abstractIn the study, a new catalyst was designed and synthesized by chemical reduction and precipitation method by impregnating the Co-Mo-B catalyst with different support materials (TiO2, Al2O3, and CeO2) in order to obtain fast hydrogen from sodium boron hydride hydrolysis. According to the support material, their catalytic activities were observed as Co-Mo-B@TiO2 > Co-Mo-B@CeO2 > Co-Mo-B@Al2O3 > Co-Mo-B. Other experimental studies were continued with the Co-Mo-B@TiO2 catalyst, which exhibited the strongest catalytic activity. BET, XRD, SEM, and EDX analyses were performed with the analytical method and their characteristics were determined. For sodium boron hydride hydrolysis of the catalyst, firstly, the optimum (Co/Mo and Co-Mo@TiO2) ratios were determined. The optimal % NaOH and NaBH4 mass concentrations, the amount of catalyst, and the effect of temperature on the hydrogen production rate were investigated. It was observed that the reaction time was shortened and the hydrogen production rate increased at 30-50 & DEG;C temperature. Kinetic parameters were calculated accordingly. The reaction rate order was determined as 0.62 from the nth order. The activation energy from the Arrhenius equation was be calculated as 40.106 kJ/mol. Hydrogen production rate at 30 & DEG;C was found to be 19.968 mL/min & BULL;g & BULL;cat.
