Abstract

Abstract : Abstract: The hydrolysis process of NaBH4 using mixed catalyst Co2 B/Pr6 O11 was studied by a drainage method. The results show that the effects of the ratios of Co2 B to Pr6 O11 and the amount of mixed catalyst Co2 B/Pr6 O11 on the amount of hydrogen release of NaBH4 are very obvious. When the doping amount is varied between 1% and 6%, the hydrogen release rate of doped samples increases firstly and then decreases as the doping amount increases. Conversely, the effect of the amount and the ratio of mixed catalyst Co2 B/Pr6 O11 on the hydrogen desorption amount of NaBH4 is not obvious. However, after NaBH4 is catalyzed by the mixed catalyst Co2 B/Pr6 O11, the hydrogen desorption amount of the sample is obviously changed and the hydrogen desorption amounts of most samples are between 410 and 525 mL. In all samples, the one doped with 4% (70%Co2 B/30%Pr6 O11 ) has the maximum hydrogen release rate of 540 mL/min and the maximum hydrogen desorption amount of 540 mL (12.1 wt%).
