Polyaniline embedded green copper oxide (Cu2O/PANI) nanocomposite has been synthesized through in situ chemical polymerization method in acidic medium at room temperature. The structural, optical, and magnetic properties of Cu2O/PANI nanocomposite were investigated through Fourier transform infrared spectroscopy (FTIR), UV-Vis absorption spectra (UV-Vis spectra), scanning electron microscopy (SEM), photoluminescence spectra (PL), and vibrating sample magnetometer (VSM). FTIR spectra confirmed the formation of Cu2O/PANI composite through the shifting of vibrational peaks of PANI and green Cu2O nanoparticles at 825, 1142, 1299, 1499, 1573 cm−1 and 695 cm−1 respectively. SEM analysis revealed that many aggregations of well-separated irregular shape of Cu2O nanoparticles with diameter about 15–40 nm exist in the composite matrix. Optical absorbance studies further confirmed the formation of composite through the blue shift of absorption peaks of PANI and diminishing intensity peak of Cu2O. Cu2O/PANI nanocomposite demonstrates semiconducting as well as diamagnetic behavior like PANI and Cu2O nanoparticles. The nanocomposite exhibits high relative photoluminescence intensity in blue as well as green-yellow region of visible spectrum. The optical band gap value from absorption coefficient data is found to be 3.23 eV.

“…The narrow bandgap of AC/Ag/TiO 2 nanocomposite acts as a better candidate material for active, visible light heterojunction with activated carbon [16]. Lower band gap value observed at AC/Ag/TiO 2 nanocomposite con rmed due to quantum con nement effect caused by nano dimensional state materials [35]. The bandgap values were well-matched with the crystallite sizes and particle sizes values.…”

In this study, AC/Ag/TiO2 nanocomposite was successfully synthesized by hydrothermal method using jasmine flower extract. The reactions of reduction, stabilization and capping was executed from the biomolecules of jasmine flower extract. The decoration of activated carbon and noble metal to the metal oxide enhanced the properties in all ways. As the modified structural, optical and morphological properties of as prepared nanocomposite was characterized using various techniques such as, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Visible spectroscopy, Scanning electron microscope (SEM) with Energy dispersive X-ray spectroscopy (EDX), and Transmission electron microscope (TEM). The photocatalytic activities under sunlight were evaluated by the degradation of methylene blue (MB). Antibacterial activity was tested against E-coli and S. aureus. The characterization results show that AC/Ag/TiO2 nanocomposite is crystalline, needle like morphology and highly optically active catalyst. The investigated AC/Ag/TiO2 nanocomposite shows 96% maximum degradation efficiency at the end of 120 minutes undervisible light irradiation. The degradation efficiency and antibacterial activity is readily higher than that of commercial TiO2. The plasmonic support to the activated carbon and titanium nanoparticles creates large surface area, active sites and accelerated the free radical generation. These characteristics demonstrated that the prepared AC/Ag/TiO2 nanocomposite material is highly suitable for the decomposition of methylene blue and waste water treatment.
