摘要:
A novel photocatalyst of Bi3.64Mo0.36O6.55 doped with Tm3+/Yb3+ was prepared by a simple coprecipitation method followed by a calcination technology. The as-synthesized Tm3+/Yb3+-Bi3.64Mo0.36O6.55 samples were characterized by various analytical methods. The as-synthesized sample exhibited enhanced photocatalytic activity when degrading Rhodamine B under the irradiation of visible-light. The photocatalytic degradation efficiency of Tm3+/Yb3+-Bi3.64Mo0.36O6.55 (95.2%) was higher than that of pure Bi3.64Mo0.36O6.55 (85.2%) in 50 min. Besides, the sample revealed a stable photocatalytic property after four photodegradation cycles. Therefore, this study may provide a better method to obtain stable upconversion photocatalyst degrading organic pollution with greatly improved activity.
