Green chemistry approach for the synthesis of CuO nanostructure

Molecular sieves MCM-۴۱ were synthesized from rice husk ash (RHA) as alternative sources of silica. The material was synthesized by a room temperature method from a gel with the molar composition SiO۲: ۱.۶EA: ۰.۲۱۵HDTMABr: ۳۲۵H۲O with pH correction. The cetyltrimethylammonium bromide (CTMABr) was used as a structure template. Nanocomposite containing ۵.۰ and ۱۰.۰ wt.% of Cu was synthesized under solid state reaction. The calcinations of samples were done at two different temperatures, ۴۰۰ and ۶۰۰◦C. The morphology and the physicochemical properties of the prepared samples were investigated by X-ray diffraction (XRD), UV–Vis diffuse reflectance spectroscopy (UV–Vis DRS), Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). TEM images indicated that nanoparticles size of CuO is ~ ۳ nm.
