In another approach, Huang et al. reported a one-step hydrothermal synthesis of a BiIO4/Bi2MoO6 hybrid photocatalyst for photodegradation of RhB dye [56]. Under visible-light irradiation

• (λ > 420 nm), photoelectrochemical studies demonstrated that the RhB photodegradation effectiveness and photocurrent density of the BiIO4/Bi2MoO6 hybrid composite is much higher than that of the pure components. Because of the successful construction of the BiIO4/Bi2MoO6 hybrid, the photocatalytic
