The invention provides a carbon dioxide hydrogenation reduction catalyst and a preparation method thereof, and belongs to the technical field of carbon dioxide conversion. The catalyst takes iron and molybdenum as active elements, the prepared iron molybdate can improve the stability of the catalyst, volcanic rock powder easy to obtain in the nature is used as a carrier, the carbon dioxide hydrogenation reduction catalyst is obtained, the process of synthesizing methane from carbon monoxide and hydrogen is inhibited, the efficiency of reducing carbon dioxide through hydrogen is improved, and the catalyst is suitable for industrial production. The catalyst preparation process is simplified, and the catalyst cost is reduced. 本发明提供了一种二氧化碳加氢还原催化剂及其制备方法，属于二氧化碳转化技术领域。所属催化剂以铁和钼作为活性元素，制成的钼酸铁可以提高催化剂稳定性，利用大自然易获取的火山岩类粉末作为载体，获得一种二氧化碳加氢还原催化剂，抑制一氧化碳和氢合成甲烷的过程，提高氢气还原二氧化碳效率，简化催化剂的制备过程，降低催化剂成本。
