In summary, nanoflaky Te-doped Bi2MoO6 photocatalyst has been synthesized via a facile hydrothermal route, and nonmetal atoms Te are successfully incorporated into the Bi2MoO6 lattice with the substitution of Te4+ to Mo6+. Te-doping does not cause the detectable band gap narrowing of Bi2MoO6. However, inhomogeneous lattice distortion is determined to be more and more severe with increasing Te-doping concentration in Bi2MoO6, presenting larger changes in lattice parameter b and smaller changes

Te-doped Bi2MoO6photocatalyst was hydrothermally synthesized, and nonmetal atoms Te were homogeneously incorporated into Bi2MoO6lattice with the substitution of Te4+to Mo6+. With increasing Te-doping concentration in Bi2MoO6, no detectable band-gap narrowing but more and more severe inhomogeneous lattice distortions were determined. The activity of Bi2MoO6photocatalyst was evaluated through methylene blue degradation under visible light irradiation (λ>410 nm) and was greatly enhanced by Te-doping. When Te-doped Bi2MoO6was synthesized at Te/Mo molar ratio of 7.5%, a maximum first...
