Carbon dioxide reduction catalyst and carbon dioxide reduction method

Abstract

The present invention provides a carbon dioxide reduction catalyst that is used in reduction reactions of carbon dioxide and that has high methanol selectivity. A carbon dioxide reduction catalyst according to the present invention is used in producing methanol by reduction reactions of carbon dioxide, and contains Au and Cu as catalyst components and ZnO as a carrier. It is preferable that the catalyst components contain 7-25 mol % of Au as a catalyst component. This makes it possible to obtain high methanol selectivity—for example, selectivity of not less than 80%. The carbon dioxide reduction catalyst makes it possible to obtain high methanol selectivity even under the conditions of not more than 240° C. and not more than 50 bar.
