随着“双碳”目标的提出,二氧化碳(CO_(2))减排和资源化利用受到研究者的广泛关注。CO_(2)耦合绿氢技术制高附加值化学品是CO_(2)资源化利用的有效途径之一。高碳α-烯烃是重要的化工原料,围绕非均相催化体系催化CO_(2)加氢制高碳α-烯烃的相关研究,总结分析了CO_(2)加氢制高碳α-烯烃的催化剂设计理念、反应机理、助剂、载体以及制备工艺对催化剂催化性能的影响和构效关系。其中,设计高效催化剂有效调控C—O键活化和C—C链增长仍存在挑战。对CO_(2)加氢制高碳α-烯烃的发展方向进行了展望,可为CO_(2)加氢制高碳α-烯烃新型催化剂的开发提供参考。

With the proposal of“carbon peaking and carbon neutrality”goals,carbon dioxide(CO_(2))emission reduction and resource utilization have attracted extensive attention from researchers.The production of high value-added chemicals by CO_(2) coupled with green hydrogen technology is one of the effective ways of CO_(2) resource utilization.The high carbonα-olefin is an important chemical raw material.Based on the research on the production of high-carbonα-olefin from CO_(2) hydrogenation by heterogeneous catalytic system,the influence of catalyst design concept,reaction mechanism,promoter,support and preparation process on the catalytic performance and the structure-activity relationship were summarized and analyzed.Among them,there are still challenges in designing efficient catalysts to effectively regulate C—O bond activation and C—C chain growth.The development direction of CO_(2) hydrogenation to high carbonα-olefins was prospected,which can provide a reference for the development of novel catalysts for CO_(2) hydrogenation to high carbonα-olefins.
