Claim Text:
1. A method for preparing a visible-light-responsive photocatalyst for photocatalytic oxidation desulphurization, which is comprised of one type of metal M I , one type of metal oxide M II Q x and BiVO 4 as a supporter, wherein the mass ratio of the sum of the two types of metal (M I +M II ) to BiVO 4 is from 1:5000 to 1:50; the mass ratio of the type of metal M I to the type of metal M II is from 1:50 to 50:1; wherein the metal M I is selected from a group consisting of Pt, Pd, and Au, and the metal M II is selected from a group consisting of Ru and Ir, wherein the method comprises steps of: a) firstly preparing BiVO adding bismuth salt and vanadic salt with the mol ratio of 1:0.5 to 1:2 into 2 M HNO b) impregnating the BiVO c) mixing the suspension and an aqueous solution containing soluble salts of metal M
