Abstract

Multiwall carbon nanotubes (MWCNTs) enhanced Co-Ni catalysts for NaBH4 hydrolysis were developed and produced in this research. The microscopes utilized was transmission electron microscope. The various species located at the surfaces of some selected catalysts has been characterized using the X-ray photoelectron spectrometer. The results reveal that even with the addition of carbon nanotubes as a promoter, the catalysts maintain an amorphous shape. In Co-Ni catalysts (NiCo@MWCNTs), however, the right amount of MWCNTs promoter results in a large specific surface area, fine dispersion of active components, more active sites, and a high electron density at active sites. Furthermore, hydrogen overflow on the catalyst is encouraged, which aids in active site regeneration and accelerates the catalytic cycle. When compared to other formulations, samples containing 5 wt% Ni and 5 wt% Co had the best catalytic activity and in this experiment, we studied the effect of different quantity of NiCo@MWCNTs (5, 10, 15, 20 mg) with keeping the other parameters are constant, different starting concentrations of SBH [NaHB4] = 1, 2, 3, and 4 M (50, 100, 150 and 200mg SBH in 50ml water). and NiCo@MWCNTs towards hydrolytic dehydrogenation of SBH over a temperature range of 35-65 oC. and we have concluded that  the best case to released 116 ml of hydrogen from SBH when we use 1.35 mmol at 5 mg catalyst at 12 min at 338 K and the activation energy . And the value of  carries from 13.907  at 35 oC to     at 45 oC. This mean that the spontaneity of the hydrogen production increased with temperature.
