Abstract
For catalytic hydrolysis of NaBH4 solution, Co-Ni/MWCNTs catalysts were prepared by chemical reduction of aqueous sodium borohydride with cobalt chloride and nickel chloride. Using MWCNTs as support is favorable to the scattering of the Co-Ni, resulting in increasing active surface area and enhancing catalytic activity, as demonstrated by calcination of the generated catalyst at 800 oC for 2 hours in a nitrogen atmosphere. When using a small amount of the catalyst, the results are clear in terms of the amount of hydrogen produced and the rate of hydrogen production; the more catalyst we use, the higher the rate of hydrogen production and the amount of hydrogen produced. Considering the temperature effect; increasing temperature leads to speeding up the rate of hydrogen production and the amount of hydrogen gas produced in the presence of the catalyst. This allows us to save energy and protect the environment in addition to saving money in the industry by reducing the amount of energy needed, eliminating the lost time, and raising the quantity of gas needed. Finally, we found that the best case was releasing 116 ml of hydrogen from NaBH4 when we used 1.35 mmol of NaBH4 (max. H2 = 120 ml) with 5 mg of catalyst for 12 min at 338 K and the activation energy E_a=53.54964 kJ/mol. and the value of ∆G varied from 13.907 kJ/mol at 35 oC to 10.307 kJ/mol at 65 oC. This means that the spontaneity of the hydrogen production increases with temperature.
