▎ 摘  要

NOVELTY - Composite photocatalyst material comprises graphene oxide and stratiform and cerium ytterbium oxide complex (CexYbyO2) (I), where x is greater than 0 and less than or equal to 1, where the value range of y is 0.01, y is less than or equal to 1, and the composite photocatalyst forbidden band width is 3.16-2.85eV. USE - Used as composite photocatalyst material. ADVANTAGE - The method is simple and has high yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite photocatalyst material using soluble cerium salt, soluble ytterbium salt, dissolving in alkaline solution, mixing, stirring to precipitate light yellow, to obtain mixed liquid and graphene oxide suspension, carrying out hydro-thermal reaction at 160-180 degrees C , reacting for 8-6 hours to obtain the product.
