The stable Ni(OH)(2) ultrafine nanosheet combined with Bi2MoO6 to form heterojunction have been fabricated successfully by a simple and mild one-step solvent-thermal method. In this work, the Ni(OH)(2)/Bi(2)MoO(6)heterojunction increased the absorption range of visible light compared to the pure Bi2MoO6, from the UV-visible diffuse reflectance spectrum (DRS), thus greatly improving the degradation rate of organic dyes. The Ni(OH)(2)/Bi2MoO6 heterojunctionwith different proportions was prepared by a mild one-step solvothermal method by controlling the mass fraction ratio between the nickel source and the bismuth source. The morphology and structure of the heterojunction materials were characterized by afield emission scanning electron microscopy (SEM) and a field-emission high-resolution transmission electron microscope (TEM). In this experiment, the photocatalytic properties were demonstrated by the degradation of organic dye Rhodamine B by the prepared samples. The results showed that 2%Ni(OH)(2)/Bi2MoO6 composite had the strongest photocatalytic performance and the maximum degradation rate was about 98% (135 min) when the Rhodamine B was degraded by visible light irradiation. It also can be found that Bi2MoO6 composited by Ni(OH)(2) ultrafine nanosheet, compared with pure Bi2MoO6, the photocatalytic performance is improved by decreasing the recombination rate of photogenic carriers.
