Operational Parameters

Single, binary and ternary nanomaterials were synthesized by precipitation, solvothermal, simple solution and impregnation methods to serve as photocatalysts. The crystal structure, morphology, band gap energy, functional groups and optical properties of these materials were characterized by XRD, SEM-EDX, UV-Vis, FTIR, and PL instrumental techniques, respectively. Photocatalaytic degradation performances of all the as-synthesized photocatalysts were investigated under visible light irradiation using MO as a model organic pollutant. The photocatalytic degradation performances of all the photocatalysts were evaluated on aqueous solution of the model pollutant dye as well as on a real sewage sample solution collected from Bahir Dar Textile Share Company. Results suggested that the optimized ternary nanocomposite photocatalyst exhibited a relatively higher efficiency towards the photodegradation of both the methyl orange (MO) dye solution (90%) and the real sewage sample solution (71.2%). The effect of operational parameters such as pH (4), initial dye concentration (10 mg/L) and photocatalyst load (0.2 g/L) in MO dye degradation were investigated by using the ternary CdS/UiO-66/Ag3PO4 (R4) nanocomposite.                     KEY WORDS: Metal-organic frameworks, Nanocomposite, Ternary system, Photocatalysts, Methyl orange   Bull.

Cuo Nanorods

In the recent years, green synthesis of nanomaterials has received a great attention to researchers in worldwide due to eco-friendly and scalable synthesis. Here, we report a green synthesis of copper oxide (CuO) nanorods via sonochemical assisted approach. The crystalline structure, band gap and morphology of as prepared CuO nanorods were investigated by UV-Vis diffuse reflectance (UV-Vis/DRS), Fourier Transform infrared spectroscopy, powder X-Ray diffraction (XRD) pattern and scanning electron microscopy (FESEM-EDX). The bandgap of as prepared CuO nanorods was found to be 2.0 eV, which is fall in the visible region of solar spectrum. FTIR demonstrated that there is strong interaction between Cu and oxygen in prepared CuO. XRD results reveal the formation of phase pure and crystalline CuO. FESEM images clearly show the rod like morphology of CuO and the presence of elemental copper and oxygen in EDX, confirms the formation of CuO. The photocatalytic degradation activity of CuO nanorods was examined against a model dye pollutant, nitrobenzene (NB) under visible light irradiation. CuO nanorods were effectively degraded the NB under visible light irradiation. CuO nanorods acts as potent and shows enhanced antimicrobial agent against pathogenic fungi, Candida albicans and bacteria, Escherichia coli.
