Fluorination of CN x Nanotubes

Multiwall CN x nanotubes have been prepared by thermal decomposition of acetonitrile over Co/Ni catalytic particles. The fluorination of nanotubes was performed at room temperature by using a gaseous mixture of BrF 3 and Br 2 . Transmission electron microscopy (TEM) and x-ray diffraction (XRD) indic...

Description
Summary:Multiwall CN x nanotubes have been prepared by thermal decomposition of acetonitrile over Co/Ni catalytic particles. The fluorination of nanotubes was performed at room temperature by using a gaseous mixture of BrF 3 and Br 2 . Transmission electron microscopy (TEM) and x-ray diffraction (XRD) indicated that only the outer shells of CN x nanotubes were fluorinated, whereas the inner shells remained intact. X-ray photoelectron spectroscopy (XPS) showed an oxidation of pyridinic-type nitrogen with tube fluorination.
