Description:
A facile microwave (MW) method is described that accomplishes alignment and decoration of noble metals on carbon nanotubes wrapped with carboxymethyl cellulose (CMC). Carbon nanotubes (CNTs) such as single-wall (SWNT), multi-wall (MWNT) and Buckminsterfullerene (C-60) were well dispersed using sodium salt of CMC under sonication and then addition of respective noble metal salts generated noble metal decorated carbon nanotube composites at room temperature. However, aligned nanocomposites of carbon nanotubes could only be generated by exposing the above nanocomposites to MW irradiation. The carbon nanotube composites were characterized using scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray mapping, transmission electron microscopy (TEM) and UV-visible spectroscopy. The general preparative procedure is versatile and provides a simple route to manufacturing useful metal-coated carbon nanotube nanocomposites.
