摘　　要：利用可再生氢气实施CO2直接加氢生成低碳烯烃或芳烃等基础化学品可同时实现碳减排和CO2的资源化利用.然而,由于CO2的C=O键难以活化且生成多碳产物的C-C偶联难以控制,导致CO2加氢易生成C1产物,选择性转化为多碳化学品较困难. 2016年,我国科学家报道了利用复合氧化物与分子筛耦合的双功能催化剂接力催化合成气制备低碳烯烃和芳烃的新路径.受此启发,近期接力催化CO2为低碳烯烃和芳烃的研究报道不断涌现.本文概述了近年有关应用双功能催化剂催化CO2加氢制高值化学品的研究进展,阐述了如何串联两个"性格"迥异的反应,并讨论了双功能催化剂上影响催化性能的关键因素.Hydrogenation of CO2 using renewable hydrogen to build block chemicals, such as lower olefins and aromatics, not only mitigates the CO2 emissions, but also realizes the utilization of CO2 as a carbon resource. However,it is difficult to activate the inert CO2 and precisely control the C–C coupling. As a result, the hydrogenation of CO2 mainly produces C1 product, and selective synthesis of hydrocarbon chemicals with C–C chains is challenging. In 2016,Chinese scientists first reported the relay catalysis, in which metal oxides and acidic zeolites were integrated together as bifunctional catalysts, for converting synthesis gas to lower olefins and aromatics. Inspired by this, a number of bifunctional catalysts have been recently reported for the hydrogenation of CO2 to lower olefins and aromatics, using the concept of replay catalysis. In this review, we summarize the recent advances in the transformation of CO2 to high-value chemicals and try to clarify how to connect two reactions with different characteristics. The key factors that affect the product distribution are also discussed.
