Investigation of Hydrogen Production Performance Using Nanoporous NiCr and NiV Alloys in KBH4 Hydrolysis

Studies of storage and production hydrogen, which is an alternative to fossil fuels, have been intensified. Hydrogen from metal borohydrides via catalyst very attractive because its advantages, such as controlled production, high hydrogen content, nontoxicity, etc. In this study, the catalytic performances nanoporous nickel–chromium alloy nickel–vanadium catalysts prepared with magnetron sputtering in hydrolysis potassium borohydride, a material, were investigated. Parameters that affected reaction rate, temperature, amount catalyst, volume 0.5 M HCl solution investigated using response surface methodology. addition, characterized XRD FE-SEM analysis, remaining solutions after reactions FE-SEM/EDS analysis. Using methodology, optimum conditions for maximum rate determined be 1.65 g 6% KBH4, 3% NaOH, 7 mL at 333 K. Under these conditions, rates calculated 68.9 L·min−1·gcat−1 76.5 NiCr NiV, respectively.
