(a) Time effluence on photocatalytic degradation of Rhodamine B dye using TiO₂ : Ga nanoparticles as the photocatalyst under UV irradiation. Inset represents the digital photographs of dye solution at different irradiation times to show color change due to photocatalytic degradation of R^hB. (b) Pseudo-first-order kinetic plots and apparent rate constant of R^hB degradation.
