Abstract: An electroless deposition route was employed to incorporate high density palladium nanowire arrays into the pore channels of mesoporous thin films(MTFs) which served as templates. The hydrophobic core of direct agent of MTFs was utilized as a carrier to introduce hydrophobic compound of palladium metal into the inner surface of MTFs. After pyrolysis and reduction by hydrogen, the catalysis centers were obtained to initiate the electroless deposition process, which avoid the complicated procedures of conventional electroless deposition. The results indicate that the synthesized nanowires have been fully filled into the pore channels of MTFs with a uniform size and an aspect ratio higher than 60. The diameter of nanowires could be adjusted via the selection of the different mesoporous templates.
