| Abstract: | For hydrogen generation from an aqueous alkaline NaBH4 solution,a novel biomass precursor for the production of Co/AC catalyst was studied in this investigation.To design a hydrogen generator,the hydrogen generation rate was measured using the Co/AC catalyst as a function of calcination time,calcination temperature and impregnation mass ratio of CoCl2/AC.The SEM and XRD analysis reveals that the prepared catalyst consisting of crystalline form of Co(OH)2 has a good dispersion and coating condition.With increasing solution temperature,the hydrogen generation rates increases.The activation energy for the NaBH4 hydrolysis reaction is calculated to be 37.4 kJ/mol. |
