Abstract

Shaped catalysts are crucial for technological applications. In this context, we have developed Co-αAl 2 O 3 catalyst films deposited over Cu plates to be used in hydrogen generation by hydrolysis of sodium borohydride NaBH 4 in alkaline solution. The Co-αAl 2 O 3 films were prepared by electrophoretic deposition according to six different routes. While five of them failed in fabricating adhering films, the sixth route, consisting of electrodepositing Co-impregnated αAl 2 O 3 , showed promising results. The as-obtained shaped catalysts were stable when hydrogen vigorously bubbled and catalyzed the NaBH 4 hydrolysis with attractive hydrogen generation rates. These results open an alternative route for preparing shaped catalysts in this reaction.
