In this study, gallium oxide (Ga2O3) nanoparticles were synthesized by sonochemical techniques at room temperature. We investigate the ultrasound irradiation conditions and the solvent type to synthesize Ga2O3 nanoparticles. γ-Ga2O3 nanoparticles were synthesized by irradiating gallium metal with ultrasound in hydrazine monohydrate solvent. The irradiation of hydrazine with ultasound suppresses the generation of ·OH, and GaOOH was not formed, and gallium metal directly oxidized. When the synthesized γ-Ga2O3 nanoparticles were heat-treated, a transition to β-Ga2O3 was observed. The heat-treated Ga2O3 nanoparticles showed excellent photocatalytic activity for the decomposition of RhB under UV irradiation.
