摘要: Abstract A prerequisite for the development of photocatalysis techniques is to obtain catalysts with remarkable activity. The construction heterojunctions an efficient way upgrade photocatalytic Herein, Bi2MoO6 microspheres composed numerous nanosheets were used construct Ag2MoO4/Bi2MoO6 via chemical deposition. Ag2MoO4 nanoparticles average size ∼8 nm well dispersed on Bi2MoO6. catalytic performance and relevant samples investigated in degradation Rhodamine B (RhB) methylene blue (MB) dye under visible light irradiation (λ > 420 nm). (30 mg) was more active than (30 mg), a physical mixture 0.9 mg 29.1 mg Bi2MoO6, it exhibited good recyclability. excellent activity due separation photogenerated electron–hole pairs. holes (h+) superoxide radical anions (O2−) are primary reactive species responsible RhB.
