ZnO/CdO rodlike nanocopmposites were successfully synthesized by using the hydrothermal method in the ionic liquid medium (4-methylpyridine,2,2,2-trifluoroacetate). The heterojunction structure of photocatalyst and nanorod structures of ZnO attached to nanoparticels of CdO improved the performance of it compared to pure ZnO and nanoparticles of ZnO/CdO. The conventional hydrothermal method was performed for the synthesis of these ccomposites. The average thickness of nanorods was 53 nm. The samples were characterized by XRD measurements, scanning electron microscopy (SEM), photoluminescence spectroscopy (PL), diffuse reflectance spectroscopy (DRS), BET, X-ray photoelectron spectroscopy (XPS). The photocatalytic performance of the heterojunction photocatalyst was investigated by using photocatalytic reactor for degradation of air pollutants (SO2, NOx). (C) 2016 Elsevier GmbH.
