Effect Of NaoH In Hydrogen Production From NaBH4 By Using Co-B-F And Co-B-P Catalysts

Mehmet Sait İZGİ, Ömer ÖDEMİŞ, Ömer ŞAHİN, Cafer SAKA


In this study, Co-B-F and Co-B-P catalysts were synthesized in order to produce hydrogen from sodium boron hydride hydrolysis. Sodium hydroxide concentration in hydrogen production from sodium boron hydride is immensely important to stabilize the reaction. In the case of over use of sodium hydroxide, catalytic activity of the catalyst will decrease, On the other hand, In the case of under-use or without any usage of the catalyst, sodium boron hydride degradation will occur. For these reasons, optimum sodium hydroxide concentrations were determined in the case of synthesized Co-B-F and Co-B-P catalysts usage in sodium boron hydride hydrolysis. In the presence of different sodium hydroxide concentrations, reaction rates and reaction rate constants were examined separately which hydrolysis of sodium borohydride with sodium hydroxide concentration was determined to be effective and how important the hydrogen production. Co-BF in the presence of catalyst for hydrogen production rate of 2.5% concentrations of NaOH in 2400 ml / dk.catalyst, Co-BP for the catalysts was 1605 ml / dk.catalyst was determined.
