ABSTRACT
Carbon nanotubes (CNTs) are being studied for a variety of applications due to their outstanding mechanical, chemical, electrical, and optical properties (Baughman et al. 2002; Popov 2004; Belin and Epron 2005). In addition, CNTs’ structures are being modied to expand their use in new applications (Baughman et al. 2002; Hirsch 2002; Raghuveer et al. 2006; Hou et al. 2008; Rashidi et al. 2010). Decorating CNTs with certain metal nanoparticles is a promising option for catalysis (Wildgoose et al. 2006), hydrogen storage (Cheng et al. 2001; Hou et al. 2003; Sarkar and Banerjee 2004; Zacharia et al. 2005; Strobel et al. 2006; Chen et al. 2008; Rakhi et al. 2008; Suttisawat et al. 2009; Yuruma et al. 2009), and sensing (Star et al. 2006; Vairavapandian et al. 2008).
