ABSTRACT:
Copper/manganese dioxide Cu/MnO2 nanoparticles have been synthesized by hydrothermal method using CuCl2 as a precursor, KMnO4 as an oxidizing agent along with surfactants i) polyvinyl alcohol (PVA) and ii) Polyvinyl pyrolidine (PVP) in the presence of ethanol solvent. The crystalline nature and morphological behaviour of the synthesized nanoparticles were confirmed by XRD pattern and SEM. The particles size of the nanoparticles for Cu/MnO2 nanoparticles and with PVP and PVA surfactants were observed to be 35.10nm, 24.10nm and 58.93 nm respectively. UV-Vis spectrum of Cu/MnO2 nanoparticles without surfactants and with surfactants PVA and PVP were observed to be 3.26 eV, 2.53 eV and 2.75 eV respectively, among these the PVA assisted Cu/MnO2 nanoparticles has reduced band gap energy from 3.26eV to 2.53 eV respectively, among these the PVA assisted Cu/MnO2 nanoparticles has reduced band gap energy from 5.96eV to 4.96 eV (wide band Gap) that transforms insulator to near by semiconducting behavior. Thus the synthesized Cu/MnO2 nanoparticles without surfactants (5.96 eV) has high optical properties that enhance the catalytic activity on methyl orange dye removal along with NaBH4 catalyst.
