Abstract

The invention provides a monatomic catalyst for synthesizing cyclic carbonate as well as a preparation method and application of the monatomic catalyst. The monatomic catalyst comprises a zirconium dioxide carrier and rare metal monatomic doped in the zirconium dioxide carrier; the rare metal comprises niobium or samarium. When the monatomic catalyst provided by the invention is used for synthesizing cyclic carbonate, the activity is high, the stability is high, the catalytic reaction process is mild, the monatomic catalyst is easy to separate from a product, and the product selectivity is high; the corresponding cyclic carbonate can be obtained by carrying out transesterification on linear carbonate, a diol compound and the catalyst provided by the invention under mild conditions, the reaction does not need harsh conditions such as a solvent, high pressure and the like, the reaction time is short, the dosage of the catalyst is small, and the method has extremely high application value.
