英文摘要: Resource utilization of carbon dioxide for the synthesis of high value-added chemicals is of great importance to solving environment and energy problems. This project is devoted to the study of a new reaction route for the mild activation of carbon dioxide to synthesize diethyl carbonate. The project is mainly focused on solving the preparation methods of catalysts with bi-functional cycloadditon/transesterification active sites. Surface-initiated polymerization, catalyst characterization and computational simulation are empolyed as research methods. The study of scientific issues is investigated in this project as follows: synthesis law of magnetically separable polymer brush catalytic materials with poly(ionic liquid/organic base) multiple catalytic sites, coupling reaction performance of carbon dioxide, propylene oxide and ethanol, the activation mechanism of carbon dioxide, as well as the structure-activity relationship of the catalysts. It is anticipated that a new route for the activation of carbon dioxide to synthesize diethyl carbonate under mild conditions and a new method for the preparation of bi-functional magnetically separable polymer brush catalysts with cycloadditon and transesterification dual functions can be developed. This project may provide new coupling reaction routes for utilization o
