Enhanced photocatalytic performance of novel self-assembled floral β-Ga2O3 nanorods
Source abstract
Abstract
Abstract Self-assembled monoclinic phase of novel floral β -Ga 2 O 3 nanorods were prepared using reflux condensation method by controlled precipitation of metal cations with urea. The structural and morphological properties were investigated by X-ray powder diffraction, Raman spectroscopy and Scanning electron microscope. Single-crystalline nanorods with size 100 nm involved in the self-assembly process to form flowery pattern have diameter ∼1 μm with surface area 40.8 m 2 /g confirmed from transmission electron microscope and Brunauer–Emmett–Teller analysis. The band gap energy of 4.59 eV was evaluated from the UV–vis diffuse reflectance spectrum and the photoluminescence spectrum displayed the characteristic luminescence and blue-light emission peaks. Further, the photocatalytic activity of novel β -Ga 2 O 3 floral nanorods towards the photodegradation of Rhodamine B in aqueous solution under ultra violet light irradiation showed better photocatalytic activity than the commercial photocatalyst Degussa P25 TiO 2 .
