Abstract
Ag/AgBr/Bi2MoO6,a novel plasma photocatalyst,is successfully synthesized via a simple solvothermal-in situ deposition-photo-reduction method.The physical and photophysical properties of Ag/AgBr/Bi2MoO6 samples are characterized and analyzed by X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS),scanning electron microscopy (SEM),transmission electron microscopy (TEM),high resolution transmission electron microscopy (HRTEM),ultraviolet-visible diffuse reflection spectroscopy (DRS) and photoluminescence emission spectra (PL).Photocatalytic activity of Ag/AgBr/Bi2MoO6 catalyst in degradation of Rhodamine B is studied.It is found that the Ag/AgBr/Bi2MoO6 composite containing 30wt% of Ag/AgBr can give the highest photocatalytic efficiency,being 6.4 times that of pure Bi2MoO6.The high activity of Ag/AgBr/Bi2MoO6 composite can be mainly attributed to the effective separation of photogenerated electron-hole pairs induced by synergism.Based on the theory of plasma resonance effect on the surface of Ag nanoparticles,the possible mechanism that Ag/AgBr helps to improve Bi2MoO6 photocatalytic activity is discussed.
