Preparation of Sonocatalyst Fe2O3/ZnO using Sol-gel/precipitation method: characterization and removal of acid orange 7 in aqueous solution / Nur Fadzeelah A. K. and Nor Aimi Abdul Wahab

Fe2O3/ZnO composite catalyst was synthesized using a solgel/precipitation method. The synthesized samples were characterized by Xray diffraction (XRD), scanning elctron microscope (SEM) with energy dispersive X-tray spectroscopy (EDX) and Brunauer−Emmet−Teller (BET) method. The feasibility of Fe2O3/...
