Facile synthesis of AgCl/BiYO3 composite for efficient photodegradation of RO16 under UV and visible light irradiation

AgCl/BiYO3 composite was successfully synthesized via the aqueous precipitation method followed by calcination. The varied amount of AgCl (10, 20 and 30%) was mixed into BiYO3 via sonochemical-assisted method. The structures and morphologies of the as-prepared AgCl/BiYO3 composite were characterized...
