Controllable deposition of Ag nanoparticles on carbon nanotubes as a catalyst…

Abstract. A simple method is devised to deposit highly monodispersed Ag nanoparticles (about 5 nm) on multi-walled carbon nanotubes (CNTs), which started from an initial modification of Ag nanoparticles with benzyl mercaptan molecules. By simply tuning the relative ratio of Ag catalyst to CNTs in solution, Ag/CNT composite with different Ag content can be achieved. The as-prepared Ag/CNT c…
