The photocatalytic activity of nano-Bi2O3 was evaluated in degradation of rhodamine B (RhB) as a model of dye pollutant from waste waters. Nano sized Bi2O3 was synthesized using the chemical precipitation method. The as-prepared sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). Structural analysis revealed that […]
Green synthesis of cupric oxide nanoparticles (CuO NPs) has been promoted as an environmentally-friendly, cost-effective and high yield method. The CuO NPs have been synthesized by reducing copper sulphate using an aqueous flower extract of Clitoria ternatea. The UV-visible peak observed at 251 nm confirmed the formation of CuO NPs. The optical bandgap energy value […]
