“Background With the development of nanotechnology, complex micro/nanodevice assembly would gradually be a reality in the future. The various explorations in the aspects Palmatine of nanomaterial preparation and performance at present provide the base for nano-engineering, in which the controllable preparation and unique performance of nanomaterials have been the keys of exploration. With the aim of exploiting new coupling phenomena and potential applications, nanocomposites have attracted much attention over the past decade [1–5]. The typical preparation way is through an in situ fabrication; the different components are integrated together to form a nanocomposite at the same time. For example,
metallic nanocrystals could be incorporated into one-dimensional (1D) carbons to form a metal-carbon nanocomposite via an organometallic precursor-controlled thermolysis approach. Unprecedented physical and chemical properties become available due to the effects of spatial confinement and synergetic electronic interactions between metallic and carbonaceous components [6]. This type of nanocomposite has shown unique properties in some aspects including magnetic, catalytic, electronic, and thermoelectric properties [7–10]. Another preparation way is the surface recombination of several different individual nanomaterials using a physical or chemical method. Due to the complexity and importance of the nanomaterial surface property, this type of nanocomposite can more easily show the new phenomenon and unique performance.
