In Situ Synthesis of Highly Dispersed Silver Nanoparticles on Multiwalled Carbon

摘要

Since their discovery, carbon nanotubes (CNTs) have been continuously attracting extensive interests in many areas of science and technology and have been the focus of current research for many years due to their unique structure-dependent optical, electrical, and mechanical properties. Recently, silver decorated CNT hybrids are increasingly attracting extensive attention due to their potential applications as catalyst, broad-band optical limiters, electrodes, and advanced materials. Hybrid systems of nanomaterials may have collective properties that are drastically different from a simple combination of individual components. Therefore, many approaches and strategies, including the solid-state reaction, vaporizing deposition,surface chemical reduction, electrochemical deposition, γ-irradiation, and other synthesis routes, have been attempted to attach silver nanoparticles (NPs) or nanoclusters on the functionalized CNTs. To prepare well-constructed silver NP-decorated CNTs, however, a simple and effective route is still more desired.
