Photocatalysts with heterojunctions had attracted much attention in the field of

photocatalysis due to their strong charge separation and transfer capabilities. In this

work, a novel Bi2MoO6/Bi2WO6/MWCNTs Z-scheme photocatalyst was firstly

prepared by one-step hydrothermal method. A series of characterization results

showed that the ternary flower-like Bi2MoO6/Bi2WO6/MWCNTs photocatalyst was

successfully synthesized. The photocatalytic property of Bi2MoO6/Bi2WO6/MWCNTs

composite was evaluated by photo-degradation of reactive blue 19 (RB-19) dye under

visible light irradiation. The results manifested that Bi2MoO6/Bi2WO6/MWCNTs

composite presented the better photocatalytic property than pure Bi2WO6 and

Bi2MoO6/Bi2WO6. Additionally, in the photocatalytic process free radical and hole

scavenging experiments indicated that h+ and ·O2- played an indispensable role.

Finally, possible mechanisms for the photocatalytic enhancement of the composite

were put forward
