Oxygen vacancy mediated TiO۲ -MoS۲ Heterostructure as an efficient photocatalyst for theRhodamine B photodegradation

In this study, a heterojunction system comprising oxygen vacancies-mediated TiO۲ nanorods (TiO۲-x)modified with MoS۲ nanosheets (TiO۲-x-MoS۲) was prepared using the hydrothermal method and studied itsphotocatalytic activity toward Rhodamine B (RhB) degradation. The obtained results showed that theheterostructure significantly improved the photoinduced charge carrier separation efficiency, thereby reducinge-/h+ recombination.
