The invention belongs to the technical field of chemical synthesis, and concretely relates to a method for one-step catalytic synthesis of diphenyl carbonate from carbon dioxide and phenol. Diphenyl carbonate is synthesized through a reaction of carbon dioxide and phenol in CCl4 in a high pressure reaction kettle under the catalysis of spinel-type nanometer ferrite with a nitrogen-containing compound as an assistant. The catalyst has nanometer particle dimension and high specific surface area, has high activity in catalytic reactions, and allows the yield of diphenyl carbonate to be higher than the yield of diphenyl carbonate synthesized in the prior art. The catalyst is magnetic, can realize enrichment recovery of the catalyst and high dispersion of the catalyst in a reaction system and overcome the defect of difficulty in separation of the catalyst from the reaction system through applied magnetic field, and is of great significance in economy and society. 本发明属于化学合成技术领域，具体涉及种由二氧化碳和苯酚步催化合成碳酸二苯酯的方法。在高压反应釜内，以尖
