Photochemical deposition of Ag nanoparticles on multiwalled carbon nanotubes

A simple method for preparation of Ag nanoparticle (NP)/multiwalled carbon nanotube (MWCNT) composites using laser irradiation without a reducing agent is presented. Ag NPs were grown on MWCNTs by laser-induced photoreduction of [Ag(NH(3))(2)](+). The larger the initial [Ag(NH(3))(2)](+) concentration, the bigger the average particle size. XRD investigations revealed the well-crystallized structure of the nanoparticles. (C) 2009 Elsevier Ltd. All rights reserved.
