A method for reducing carbon dioxide, comprising the step of reacting carbon dioxide and hydrogen in the presence of a catalyst, whereby carbon monoxide and water is formed, is characterized in that the reaction is carried out at a temperature of >= 700 °C and that the catalyst comprises: (I) a metal (M1) and/or at least two different metals (M1) and (M2) on and/or in a support, the support being carbide, oxycarbide, carbonitride, nitride, boride, silicide, germanide and/or selenide of the metals A and/or B; and/or (II) reaction products of (I) in the presence of a gas mixture comprising carbon dioxide, hydrogen, carbon monoxide and water at a temperature of >= 700 °C. M1 and M2 are independently selected from the group comprising: Cr, Mn, Fe, Co, Ni, Re, Ru, Rh, Ir, Os, Pd, Pt, Zn, Cu, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and/or Lu. A and B are independently selected from the group comprising: Be, Mg, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Y, Zr, Nb, Mo, Hf, Ta, W, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and/or Lu. |
