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
