Cobalt in NaBH4 hydrolysis.
Cobalt-catalyzed hydrolysis of sodium borohydride (NaBH(4)) has attracted great attention since the hydride is believed to be promising hydrogen storage material. Cobalt is an efficient metal catalyst and has already proven to be a potential alternative to noble metals. Nevertheless it is not stable. Indeed it transforms into a Co- and B-based material when on contact with NaBH(4). Through ex s...
متن کاملKinetic study of CO desorption from cathodic electrochemically treated carbon paper supported Pt electrodes
Platinum particles were grown directly by an electrodeposition process on electrochemically treated carbon paper (CP) for kinetic study of carbon monoxide (CO) desorption. The treatment on CP was performed by applying −2 V for cathodic oxidation over 5 min. Treated CP was characterized by FTIR to investigate the oxygen groups on its surface. CO surface coverage at each temperature was determine...
متن کاملEffects of Composite Catalyst Co2B/TiO2 on Hydrolysis of NaBH4
For the purpose of improving hydrogen release capacity of NaBH4, hydrogen generation performance of NaBH4 was catalyzed by Co2B and TiO2 compound with different mole ratio and percentage composition are investigated. The experiment mainly concentrated in the hydrogen generation rate and the hydrogen generation volume. The results indicate that the effects of hydrogen release of NaBH4 when the p...
متن کاملHydrogen evolution from catalytic hydrolysis of NaBH4: Comparative study between the catalytic activity of TiO2 nanotubes with various arrangements
Nowadays, a lot of efforts have been applied to find an appropriate catalyst for generating hydrogen from NaBH4. Hence in the current study, various nanostructures of TiO2 were employed to obtain an insight into how the different support catalysts effect on the hydrolysis rate of NaBH4. For this aim, disordered filaments (DF-NTs) and ordered free-standing TiO2 nanotubes (FS-NTs) were fabricated...
متن کاملHydrogen generation from hydrolysis of sodium borohydride using sulfonated porous carbon as reagent/catalyst
The hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of H+ to NaBH4. The sulfonated porous carbon (SPC) is used as a source of hydrogen ion and catalyst. It is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of NaBH4 to generate hydrogen gas at room temperature in comparison to Amberlyst-15 and Nafion-NR50. The ki...
