AB  - Despite the availability and dedicated studies on a variety of carbon 
      nanostructures, amorphous carbon is still a preferred support for a wide range of 
      commercially available metal catalysts. In order to shed some light on this, we 
      carried out electroless deposition of metal nanoparticles on various carbon 
      nanostructures such as amorphous carbon (a-C), carbon nanotubes (CNTs), and 
      nitrogen-doped CNTs (NCNTs) under similar experimental conditions. The main 
      objective is to elucidate the preferable deposition on a particular carbon 
      nanostructure, if any, and understand the underlying mechanism. Experimental 
      results unveil preferred electroless deposition of metal nanoparticles on a-C 
      over CNTs and NCNTs. Notably, the deposition is nicely correlated with the 
      position of the Fermi level (E(F)) with respect to the M(n+) <--> M(0) redox level 
      (E(0)). Remarkably, E(F) is found to be in the following order NCNT > CNT > a-C 
      and the smaller gap (E(0)-E(F)) favors the faster electron transfer, resulting in 
      the preferential reduction of M(n+), yielding finer nanoparticles on a-C. We 
      believe that this approach can pave the way for designing noble metal-based 
      carbon nanocomposites for a variety of applications, ranging from environmental 
      redemption to electrochemical energy harvesting. As case studies, we have 
      explored the nanocomposites for various catalytic activities and found them to be 
      very competent with recently reported various state-of-the-art electrocatalysts 
      and their commercial counterparts.
