The sphere-like AgCl/Bi2WO6 composite was synthesized via two hydrofacies process.The obtained samples were characterized by XRD,SEM,DRS,XPS and PL.The samples exhibited remarkable enhanced visible-light photocatalytic degradations of an aqueous solution of methyl orange(MO).The results revealed that the prepared samples was spherical nanocrystalline AgCl/Bi2WO6 with the diameter of 700～900nm.The sample obtained with the optimal theoretical AgCl quality ratio of 70% exhibited the highest photocatalytic activity.Under visible light of 6min,the degradation efficiency of samples was 99.1% in methyl orange (MO,200mL,8mg/L),which displayed photocatalytic activity were 5.5 times than that of Bi2WO6.The degradation rate of MO could reach 91.95% after cycled for three times.Photocatalytic mechanism investigations demonstrated that the degradation of MO over AgCl/Bi2WO6 under visible light was mainly via ·OH and Cl0 oxidation mechanism.
