From: Hydrothermal Synthesis and Photocatalytic Property of β-Ga2O3 Nanorods
Photocatalytic activity of α-Ga2O3 and β-Ga2O3 under UV irradiation. Measured absorbance spectra of the RhB solution at different UV irradiation times in the presence of a (i) α-Ga2O3 and (ii) β-Ga2O3 nanorods. b Calculated constant reaction rate of the photodegradation of RhB solution (C/C 0) as a function of UV irradiation time for α-Ga2O3 and β-Ga2O3 nanorods. The photographic images of the RhB solution with β-Ga2O3 nanorods at different UV irradiation times are also shown in the inset of b
