In this work,we developed a templated self-assembly approach to fabricate self-supporting Au/TiO_2binary nanoparticles-nanotubes(NPNTs) for the first time.The stable Au/TiO_2 nanoparticles colloids were pre-synthesized and then deposited onto an AAO template,following by a mild calcination process.Au/TiO_2 binary NPNTs can be achieved after removing the AAO template by NaOH solution.In addition,Au/TiO_2 NPNTs with different thicknesses and size distributions could be achieved by tailoring the process parameters,such as the molar ratio of AuNPs to TiO_2NPs,deposition modes and calcinations conditions.Therefore,these findings made controllable formation of Au/TiO_2 NPNTs attractive for promising fabrication methodologies of metal/metal oxides NPNTs.
