description According to the reverse water gas shift catalyst and the preparation method and application thereof, the reverse water gas shift catalyst obtained on the basis of the preparation method is used for reverse water gas shift reaction, the catalytic activity is excellent, and the CO selectivity is high. The preparation method comprises the following steps: contacting a salt solution for precipitation with a precipitant aqueous solution and carrying out co-precipitation while controlling the reaction temperature to be 40-80 DEG C and the pH value to be 6-8; after the coprecipitation is finished, aging is optionally carried out; and filtering the obtained precipitate to obtain a filter cake, washing the filter cake, then drying the filter cake, and roasting at 300-500 DEG C to obtain the reverse water gas shift catalyst. Wherein the salt solution for precipitation is a mixed aqueous solution of soluble salt of divalent metal ions and soluble salt of trivalent metal ions, the divalent metal ions are selected from d
