摘要： A method for producing a hydrofluoroolefin is provided. The formation of by-products of an over-reduced product having hydrogen added to a material chlorofluoroolefin and an over-reduced product having not only chlorine atoms but also fluorine atoms in the chlorofluoroolefin replaced with hydrogen atoms is suppressed in the method. The method includes reacting a specific chlorofluoroolefin with hydrogen in the presence of a catalyst supported on a carrier to obtain the hydrofluoroolefin. The catalyst is a catalyst composed of an alloy containing at least one platinum group element of palladium and platinum, and at least one second element of copper, gold, lithium, potassium, silver, zinc, tin, lead, and bismuth.
