Ostwald ripening of platinum nanoparticles confined in a carbon nanotube/silica-templated cylindrical space

Abstract

Sintering of nanoparticles mediated by an Ostwald ripening mechanism is generally assessed examining the final particle size distributions. Based on this methodology, a general approach for depositing platinum nanoparticles onto carbon nanotubes in solution has been employed in order to evaluate the sintering process of these metallic nanoparticles at increasing temperatures in a carbon nanotube/silica-templated confined space. © 2012 Cintia Mateo-Mateo et al.
