| Abstract: | A new solution-phase method for synthesis of metal nanoparticles–carbon nanotubes (CNTs) assemblies is described. By injection of CNTs solution into the diethyl ether/aqueous solution of metal salt biphasic mixture, metal (Ag, Au, Pd, and Pt) nanoparticles–decorated CNTs composite materials can be prepared. Metal nanoparticles have spontaneously and selectively formed on the sidewalls of CNTs through redox reaction between CNTs and metal ions. This phenomenon has been probed by transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray analysis, and Raman spectroscopy. |
