Abstract

In this study aluminum oxide Al2O3 nanoparticles NPs were synthesized via an electrochemical method The effects of reaction parameters such as supporting electrolytes solvent current and electrolysis time on the shape and size of the resulting NPs were investigated The Al2O3 NPs were characterized by Fourier transform infrared spectroscopy Xray diffraction transmission electron microscopy thermogravimetric analysis/differential thermal analysis energydispersive Xray analysis and ultraviolet–visible spectroscopy Moreover the Al2O3 NPs were explored for photocatalytic degradation of malachite green MG dye under sunlight irradiation via two processes adsorption followed by photocatalysis coupled adsorption and photocatalysis The coupled process exhibited a higher photodegradation efficiency 45 compared to adsorption followed by photocatalysis 32 The obtained kinetic data was well fitted using a pseudofirstorder model for MG degradation
