Ni/La2O3 catalyst containing low content platinum–rhodium for the dehydrogenation of N2H4·H2O at room temperature

Ni/La 2 O 3 nanocatalyst with Pt and Rh content as low as 5 mol%, respectively, is successfully synthesized by a facile co-reduction method in the presence of hexadecyl trimethyl ammonium chloride aqueous solution under ambient atmosphere. Interestingly, the resulted Ni/La 2 O 3 catalyst with low cost exhibits excellent catalytic activity to dehydrogenation of hydrous hydrazine (N 2 H 4 ·H 2 O), producing hydrogen with 100% selectivity at room temperature (298 K), which represents a promising step toward the practical application for N 2 H 4 ·H 2 O system on fuel cells.
