Facile Hydrothermal Synthesis of Cu and Al Oxide Nanoparticles for Photodegradation of Chlorpyrifos.

Copper oxide (Cu₂O) and aluminum oxide (Al₂O₃) nanoparticles were successfully fabricated through a facile hydrothermal route. The stating materials were the metal salts of copper, aluminum, de-ionized water and gallic acid, where gallic acid played the role of benign stabilizing agent in the synthesis process. Crystallite size of the nanoparticles determined using Williamson Hall analysis were found to be 24 and 26 nm for aluminum oxide and copper oxide respectively.
