dc.description.abstract | A series of narrowly dispersed Pt nanoparticles of 1.5-2.2
nm in size stabilized by bulky terphenylphosphane ligands has been
synthesized by the organometallic method using [Pt(dba)2] as
platinum source. These nanoparticles are highly efficient catalysts for
hydrogen generation by methanolysis of ammonia borane (H3N∙BH3),
providing notable TOF values of up to 284 min-1 at 30 oC and low
catalyst loadings (0.14-0.19 mol%). Furthermore, catalysts separation
(after distillation of the H2-depleted ammonium tetramethoxyborate
(NH4B(OMe)4) and methanol) and recycling were proven to be
feasible, although an erosion of the catalytic activity was observed
after three catalytic runs. These Pt nanoparticles have also been used
as catalysts for tandem dehydrogenation of ammonia borane and
hydrogenation of N-heterocycles, providing the reduction products of
quinoline, phenanthridine, 2-methylquinoxaline and acridine in >90%
yields under mild reaction conditions. | es |
