Tunable and sustainable photocatalytic activity of photochromic Y-WO₃ under visible light irradiation.

ABSTRACT: Although photochromic and photocatalytic performance are the most significant features of WO₃, the effects of photochromism on photocatalytic activities have not been investigated further. Herein, a novel gear-shaped WO₃, with high coloration efficiency, fast reversibility, and remarkable photocatalytic performance was successfully prepared via a facile hydrothermal method. The influence of photochromic effects on its photocatalytic properties was evaluated under visible light irradiation. The results showed that the yellow WO₃ sample exhibited higher photocatalytic efficiencies toward tetracycline hydrochloride (TCH), oxytetracycline (OTC), rhodamine B (RhB), and ciprofloxacin (CIP) (94.3%, 87.9%, 76%, and 68.6%, respectively, in 60 min).
