Abstract:

As a rising star in the carbon family, graphene has attracted a great deal of attention in recent years because of its excellent electronic, conductive and mechanical properties, superior chemical stability and high specific surface area, as well as its potential applications in photocatalysis, energy storage, sensors, and solar cells. Recently, graphene-based composite fabrication has been a hot research topic. The introduction of new components has planted new functionalities in graphene. In particular, one attractive challenge is currently to fabricate specified architectures of graphene-base composites, and therefore a number of strategies have been put forward for the fabrication of graphene-based nanostructures. Graphene?based nanocomposites have typically been prepared by chemical or thermal reduction of mixtures of graphene (or graphene oxide) and new component precursors. Obviously, these methods involve highly toxic chemicals, high temperature, impurity, and multiple steps. Recently, we have successfully developed one-step co-electrodeposition method to fabricate graphene-based nanocomposites with craved architectures. Because the electrochemical techniques are applicable to a variety of materials, including organic, inorganic, biological, and polymeric molecules, this environmentally friendly and high-efficiency technology is generally applicable and could lead to a range of graphene-based composites with excellent properties and improved functionalities due to the synergetic effects between graphene and other components, and therefore the nanostructures have been widely used in the fields of electronics, energy storage, photocatalysis, solar cells, and sensors.
