Tailoring structural, optical characteristics of CuO/In2O3 nanoparticles-doped organic material for photodegradation of dyes pollutants.

In present work, nanocomposites films of polyethylene oxide (PEO), copper oxide (CuO) nanoparticles and indium oxide (In2O3) nanoparticles have been fabricated for discoloration and photo-degradation of dyes pollutants with high efficiency, few cost, anti-aggregation and high dispersion of nanoparticles. The structural and optical properties of PEO/CuO–In2O3 nanocomposites have been investigated. The structural properties were included the tests: optical microscopic (OM), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR). The optical properties of PEO/CuO–In2O3 nanocomposites were studied in wavelength range (200–800) nm. The results of optical properties of PEO/CuO–In2O3 nanocomposites showed the absorbance of PEO increases about 57.4% at (λ = 500 nm) and the energy gap of PEO reduces about 41.1% with adding of CuO–In2O3NPs which may be considered as a key for various optical and electronic fields. The optical constant of PEO were improved by adding of CuO NPs and CuO–In2O3 NPs. The PEO/CuO–In2O3 nanocomposites have been utilized for photo-degradation of dyes pollutants. The results showed prepared nanocomposites can be used for excellent photo-degradation of dyes with high efficiency reached 91% and low concentration of nanoparticles. [ABSTRACT FROM AUTHOR]
