Ammonia borane received extensive attention due to its hydrogen content as high as 19.6%. In present article we prepared the Pt-Co/C catalyst via ultrasonic immersion method and in situ reduction method. The catalyst was characterized by measuring the specific area. The influence of the catalyst on the properties of the hydrolysis of ammonia borane was tested, and the catalytic activity of the catalyst in cycle use was verified. Results shows that the catalytic activity of Pt0.5Co0.5/C is the highest, and the maximum hydrogen generation rate is 7229.613 mL/ (g ·min). It was verified that it remained good catalytic activity after cycle use for more than 10 times.

AbstractWater soluble poly(4-styrenesulfonic acid-co-maleic acid), PSSA-co-MA, stabilized nickel(0) and cobalt(0) nanoclusters were prepared for the first time from the reduction of nickel(II) chloride and cobalt(II) chloride by using minimum amount of sodium borohydride shortly before their usage as catalysts in the hydrolysis of ammonia-borane (AB) in the same medium at room temperature. PSSA-co-MA stabilized nickel(0) and cobalt(0) nanoclusters showed high catalytic activity in hydrogen generation from the hydrolysis of AB even at low temperature.
