Abstract:Bi2MoO6/TiO2/GO composite was successfully prepared by hydrothermal method. It had high photocatalytic activity for Rhodamine B (RhB) under visible light instead of ultraviolet light irradiation. Experimental results showed that the photocatalytic degradation rate of RhB by Bi2MoO6/TiO2/GO composite was 100% when the doping ratio of TiO2 in the composite was 10%, the dosage was 0.15 g, and the irradiation time with visible light was 120 min. Therefore, Bi2MoO6/TiO2/GO composite had a good application prospect in practical environmental treatment due to its visible light catalytic condition and high catalytic performance. |
Key words:bismuth molybdate; titanium dioxide; graphene oxide; visible light catalysis; Rhodamine B |
