▎ 摘 要
NOVELTY - The preparation method of yellow composite catalyst involves weighing molybdenum disulfide, graphene oxide and ferrous sulfate and then uniformly mixing, ultrasonically processing the mixture and heating using water bath. USE - The method is useful for preparation of yellow composite catalyst, which is useful for catalytic reduction reaction of trifluralin (claimed). ADVANTAGE - The method enables preparation of yellow composite catalyst with excellent catalytic performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of yellow composite catalyst for catalytic reduction reaction of trifluralin.
