Outline of Final Research Achievements

Facile synthesis of metal nanoparticles supported on nitrogen-doped, herringbone-type carbon nanofibers (N-CNFs), which were prepared by chemical vapor deposition using acetonitrile as carbon and nitrogen source, was accomplished by pyrolysis of metal alkene complexes such as Pd2(dba)3(CHCl3) and Pt(dba)2 [dba: dibenzylideneacetone]. Transmission electron microscopy images of these metal nanoparticle-immobilized N-CNF-Hs (M/N-CNF-Hs) showed that size-controlled metal nanoparticles existed on the N-CNF-H. Among these M/N-CNF-Hs, the Pd/N-CNF-H was probed to act as efficient poisoning catalysts for the selective hydrogenation of aromatic ketones to the corresponding alcohols, and selective hydrogenation of alkenes and nitroarenes having benzyloxy groups in the molecules without promoting the hydrogenolysis of the carbon-oxygen bond of benzyloxy groups.
While palladium particles on activated carbon showed high catalytic activity towards silane-reduction of tertiary carboxamides.
