AB  - An effective and facile in situ reduction approach for the fabrication of carbon 
      nanotube-supported Au nanoparticle (CNT/Au NP) composite nanomaterials is 
      demonstrated in this article. Linear polyethyleneimine (PEI) is ingeniously used 
      as both a functionalizing agent for the multiwalled carbon nanotubes (MWNTs) and 
      a reducing agent for the formation of Au NPs. This method involves a simple 
      mixing process followed by a mild heating process. This approach does not need 
      the exhaustive surface oxidation process of CNTs. The coverage of Au NPs on CNTs 
      is tunable by varying the experimental parameters, such as the initial molar 
      ratio of PEI to HAuCl4, the relative concentration of PEI and HAuCl4 to MWNTs, 
      and the temperature and duration of the heat treatment. More importantly, even 
      the heterogeneous CNT/Au composite nanowires are obtainable through this method. 
      TEM, XPS, and XRD are all used to characterize the CNT/Au composite materials. In 
      addition, the optical and electrocatalytic properties are investigated.
