Electrochemical preparation of aluminum oxide nanoparticles and using for remove chromotrope-E122 dye

A photocatalyst aluminum oxide Al2O3 Nanoparticles was effectively prepared by electrochemical method using electrolysis cell which contains stainless steel (1cm 2) and aluminium plate (1cm2) were worked as a cathode and anode electrodes respectively. The synthesized Al2O3 Nanoparticles sample was identified by Fourier transform infrared (FTIR), X-ray diffraction (XRD), and Field Emission Scanning Electron Microscope (FE-SEM) with (EDS) analysis. The XRD pattern specified that prepared Al2O3 sample had a crystal structure for γ-Al2O3with average crystal size (3nm) was achieved at (1000°C) calcination temperature. FTIR spectra indicated the existence of O–Al–O bonds vibration and hydroxyl group in the sample. The FESEM images gave morpholgy of Al2O3 nanoparticles powder after calcination to 1000°C was spherical shape and the particles were attached to each other, leading to an increase in particle size.  The EDS measurements indicated the presence of Al with O peaks. The experimental results of the Al2O3 photocatalyst calcined at 1000°C for two hours showed photocatalytic efficiency to degradation Chromotrope -E122 dye under UV light
