Abstract: The present invention relates to a supported copper catalyst comprising Cu, Zn, Al, Zr, Si, and O, wherein the catalyst comprises elemental copper, and wherein the catalyst displays a Zn:Si atomic ratio in the range of from 5:1 to 27:1, as well as to a precursor of the catalyst. Furthermore, the invention relates to a process for the preparation of a catalyst and catalyst precursor, respectively, as well as to a method for the conversion of CO2-containing syngas to methanol, and to a method for the conversion of syngas to dimethyl ether which respectively employ the inventive catalyst.
