The invention discloses a method for preparing a mesoporous ZnO-ZrO2 solid solution catalyst and an application of the mesoporous ZnO-ZrO2 solid solution catalyst. The method comprises the following steps: preparing a metal nitrate mixed solution and a template agent mixed solution, fully mixing the two solutions, dropwise adding the mixed solution and a Na2CO3 solution into a reaction container,continuously stirring after titration is finished, aging at the temperature of about 70 DEG C, after the aged product is cooled, centrifuging to obtain a solid precipitate, washing the solid precipitate with deionized water, drying to obtain a catalyst precursor, and finally, roasting the catalyst precursor to obtain a catalyst matrix. According to the preparation method, the pore diameter structure of the ZnO-ZrO2 solid solution catalyst is improved, the high-temperature sintering and agglomeration phenomena of the catalyst are effectively inhibited, and the catalyst has relatively high carbon dioxide conversion rate
