Multiple-wall carbon nanotubes obtained with mesoporous material decorated with ceria-zirconia

In this work, Ceria-Zirconia on ordered Santa Barbara mesoporous silica (Ce-Zr-SBA-15), has been used directly as a catalyst for the synthesis of carbon nanotubes (CNTs) through Chemical Vapor Deposition (CVD). addition to cerium oxide, it contains zirconium oxide nano crystallites, which act catalysts nanostructures. The catalytic performance material was evaluated decomposition ethanol at 900 °C, with N2 flow. decomposed from absolute diffuses surface nanostructured and precipitates in form MWCNT structures, could be identified by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) Transmission (TEM), showing average diameters 30–35 nm.
