Photocatalytic degradation of tetracycline hydrochloride over rugby-like β-Ga2O3 with a 3D hierarchically assembled porous structure for environmental remediation

A novel rugby ball-like β-Ga₂O₃ photocatalyst with a 3D hierarchically assembled porous structure was constructed via a facile precipitation–calcination method. The as-synthesized Ga₂O₃ exhibits a high photocatalytic efficiency compared to commercial Ga₂O₃ and Degussa P25.
