The invention relates to the technical field of catalysts, and discloses a quaternary ammonium salt coordination bimetallic catalyst and a preparation method and application thereof. The preparation method of the quaternary ammonium salt coordination bimetallic catalyst comprises the following step: reacting a solution containing multi-cyano metal acid potassium salt and a hydroxyl-terminated quaternary ammonium salt ligand with a metal salt solution to obtain the quaternary ammonium salt coordination bimetallic catalyst. The hydroxyl-terminated quaternary ammonium salt is used as the ligand, the quaternary ammonium salt coordinated bimetallic catalyst is directly prepared while the bimetallic catalyst is synthesized, the preparation process is simple, and the obtained quaternary ammonium salt coordinated bimetallic catalyst can be directly recycled after being filtered. The quaternary ammonium salt coordination bimetallic catalyst obtained by the invention can be used for synthesizing carbon dioxide-based cy
