The activity of cobalt–boron catalysts in sodium borohydride hydrolysis has been correlated with change of
structure in the active component of the catalysts upon their thermal treatment. It was shown that at temperatures to 300 C there takes place loss of water and hydrogen from the catalysts without noticeable changes in activity. At temperatures above 300 C the amorphous cobalt boride particles undergo crystallization to produce metallic cobalt with a hexagonal structure and this is seemingly the cause of the substantial fall in the rate of hydrogen generation in the presence of cobalt–boron catalysts.
