Optoelectronic properties of solution synthesis of carbon nanotube/ZnO:Al: N nanocomposite and its potential as a photocatalyst

摘要

A novel multiwalled carbon nanotubes/aluminum-nitrogen co-doped ZnO (MWCNT/ZnO: AI:N) nanocomposite film was synthesized by a sol-gel deposition method and used for the photodegradation of organic dye under UV light illumination. The MWCNT/ZnO:AI:N composite film was extensively characterized through scanning electron microscope(SEM), Energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence measurements (PL) and UV-vis spectroscopy. Photocatalytic measurements reveal that the addition of MWCNT enhances photocatalytic degradation of MB by providing conduction path for electron transfer and reactive oxygen groups.
