The invention discloses a double-phosphorus coordination compound of metal rhodium. The double-phosphorus coordination compound of the rhodium can be applied to catalysis of a carbon dioxide hydrogenation reaction, a strong sigma electron-drawing group is arranged on a double-phosphorus ligand, and the electron cloud of the rhodium can be increased, so that the speed of the step of catalyzing carbon dioxide hydrogenation reduction by the double-phosphorus coordination compound of the rhodium is increased, the catalytic efficiency is improved, and the reaction time is shortened.
