Abstract

Industrial wastes particularly organic dyes has been a matter of great challenge in the rapid growing industrial technologies. To address this issue nanocomposites of ZnO-Graphene, ZnO-CuO and ZnO-CuO-graphene were efficiently developed via chemical co-precipitation method and inestigated its photocatalytic properties for efficient waste water treatment in the degradation of methylene blue (MB) as an indicator. These nanocomposites were fully characterized by numerous advanced characterization techniques i.e. X-ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), UV–visible spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) Spectroscopy, and Photoluminescence (PL). The SEM image of ZnO-CuO-Graphene nanocomposite revealed flower-like morphology while the presence of Zn, Cu, O, and C were confirmed by EDX spectroscopy. Low PL intensity of ZnO-CuO-Graphene nanocomposite indicates low electron-hole recombination indicating it is a potential photocatalyst for photocatalysis application. Among all nanocomposites, ZnO-CuO-Graphene nanocomposite possesses greater photocatalytic activity after 180 min while exposed to solar light i.e. 81 % degradation of MB dye copared to 74 % and 77 % degradation by ZnO-G and ZnO-CuO nancomposites respectively. The incremental photocatalytic efficiency of the ZnO-CuO-Graphene nanocomposite is predominantly due to the larger active surface area resulting from the incorporation of Graphene.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
