• increase in the overlap between Bi 6s and O 2p orbitals, a reduced charge transfer route, and strange floating features. 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

• ] demonstrated the synthesis of a new direct Z-scheme photocatalyst made of ultrathin Bi2O3 and Bi2MoO6 microspheres. For the effective production of Bi2O3/Bi2MoO6 nanocomposites, researchers adopted a simple in situ alkali treatment of Bi2MoO6 followed by calcination. As a substrate for the production of Bi2O3

• development of visible-light-driven photocatalysts is highly desirable because visible light accounts for about 43% of the solar spectrum. Currently, bismuth-based semiconductor materials, including Bi2O3 [4], BiVO4 [5][6], Bi2WO6 [7], Bi2MoO6 [8], BiOX (X = Cl, Br, I) [9], and Bi2O2CO3 [10], are explored as

The enhancement of activity was

• attributed to the high charge-separation capacity, which results from the matched band alignment of the two components. The cycling experiments showed a good durability of Ag2CO3/Bi2MoO6. Holes were found to be the dominant active species accounting for the pollutant degradation. This compound is a promising
