Developing catalyst to create a feasible system for NaBH4 hydrolysis would increase the widespread use of clean energy producing fuel cell system. However, transfer difficulties such as; three phase reaction mechanism and reactant-side product solubility problems limit the promising properties of the hydrolysis systems. In this study Co1-xMnx bimetallic catalyst was produced and adhered on TiO2 support by co-reducing method. Optimum NaOH concentration for the catalyst and reaction conditions was determined before the studies. In the experiments it was proved that only 40 mg of Co0.7Mn0.3/TiO2 catalyst is highly active to decompose NaBH4 at 20 °C. SEM-EDX results revealed that the catalyst homogeneity and active sites existence are valid after reaction. Released hydrogen was collected by inverse burette apparatus and maximum hydrogen generation rate was calculated as 43.6 at 20 °C. Investigations resulted that the reaction obeys first order kinetic on the basis of NaBH4 and the activation energy is 38.7 kJ.mol-1.
