    摘要: This invention relates to a visible-light-responsive photocatalyst for photocatalyticly oxidation desulphurization and method for preparation and application thereof. The catalyst is comprised of one type of metal MI, one type of metal oxide MIIOx and BiVO4 as the supporter, wherein the mass ratio of the sum of the two types of metal (MI+MII) to BiVO4 is from 1:5000 to 1:50; the mass ratio of the type of metal MI to the type of metal MII is from 1:50 to 50:1. The catalyst is used in the photocatalytic oxidation desulphurization. Under mild condition (room temperature, 1 atm), using O2 as the oxidant and xenon lamp (wavelength 420 nm
