摘要： A monolithic catalyst used for a carbon dioxide hydrogenation reaction and a method for preparing the same. The catalyst comprises a carrier, a coating, and active components. The carrier is a honeycomb ceramic. The coating and the active components are separately applied to honeycomb ceramic hole walls from inside to outside. Moreover, each of the honeycomb ceramic holes is divided into an upper segment and a lower segment, and different active components are separately loaded on the two segments. The method for preparing the monolithic catalyst comprises first applying a coating to a honeycomb ceramic by means of impregnation to obtain a coating-containing carrier, and then applying active components to an upper segment and a lower segment of the coating-containing carrier successively by means of impregnation to obtain the monolithic catalyst.
