Nickel(0) nanoparticles supported on bare or coated cobalt ferrite as highly active, magnetically isolable and reusable catalyst for hydrolytic dehydrogenation of ammonia borane.
Journal of Colloid and Interface Science 2017 December 16
Nickel(0) nanoparticles supported on cobalt ferrite (Ni0 /CoFe2 O4 ), polydopamine coated cobalt ferrite (Ni0 /PDA-CoFe2 O4 ) or silica coated cobalt ferrite (Ni0 /SiO2 -CoFe2 O4 ) are prepared and used as catalysts in hydrogen generation from the hydrolysis of ammonia borane at room temperature. Ni0 /CoFe2 O4 (4.0% wt. Ni) shows the highest catalytic activity with a TOF value of 38.3min-1 in hydrogen generation from the hydrolysis of ammonia borane at 25.0±0.1°C. However, the initial catalytic activity of Ni0 /CoFe2 O4 catalyst is not preserved in subsequent runs of hydrolysis. Coating the surface of cobalt ferrite support with polydopamine or silica leads to a significant improvement in the stability of catalysts. The TOF values of Ni0 /PDA-CoFe2 O4 and Ni0 /SiO2 -CoFe2 O4 are found to be 7.6 and 5.3min-1 , respectively, at 25.0±0.1°C. Ni0 /PDA-CoFe2 O4 catalyst shows high reusability as compared to the Ni0 /CoFe2 O4 and Ni0 /SiO2 -CoFe2 O4 catalysts in hydrolytic dehydrogenation of ammonia borane at room temperature. All the catalysts are characterized by using a combination of various advanced analytical techniques. The results reveal that nickel nanoparticles with an average size of 12.3±0.7nm are well dispersed on the surface of PDA-CoFe2 O4 . .
