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 proportions and amount of Co2B/TiO2 are not obvious.
Changing the proportions and the amount, the amount of hydrogen release by hydrolysis of NaBH4 are between 343-
375ml. However, the study on the rate of hydrogen release finds that the effects of the proportion and amount of the
compound catalyst on the rate of hydrogen release are very marked. The rate of hydrogen release of the catalyst samples
presents an obvious increase when the amount of Co2B/TiO2 is between 1-4%. Among all the samples of compound
catalyst, the rate of hydrogen release of the sample with 5% Co2B/2TiO2 is the largest.
