The emerging process of CO2 hydrogenation through heterogenous catalysis into important bulk chemicals provides an alternative strategy for sustainable and low-cost production of valuable chemicals, and brings an important chance for mitigating CO2 emissions. Direct synthesis of the family of unsaturated heavy hydrocarbons such as α-olefins and aromatics via CO2 hydrogenation is more attractive and challenging than the production of short-chain products to modern society, suffering from the difficult control between C–O activation and C–C coupling towards long-chain hydrocarbons. In the past several years, rapid progress has been achieved in the development of efficient catalysts for the process and understanding of their catalytic mechanisms. In this review, we provide a comprehensive, authoritative and critical overview of the substantial progress in the synthesis of α-olefins and aromatics from CO2 hydrogenation via direct and indirect routes. The rational fabrication and design of catalysts, proximity effects of multi-active sites, stability and deactivation of catalysts, reaction mechanisms and reactor design are systematically discussed. Finally, current challenges and potential applications in the development of advanced catalysts, as well as opportunities of next-generation CO2 hydrogenation techniques for carbon neutrality in future are proposed.

向 CO2 多相加氢生成高价值不饱和重烃的新兴工艺发展
通过多相催化将CO 2氢化成重要大宗化学品的新兴工艺为有价值化学品的可持续和低成本生产提供了一种替代策略，并为减少 CO 2排放带来了重要机会。通过CO 2直接合成不饱和重烃家族，例如 α-烯烃和芳烃对于现代社会来说，加氢比短链产品的生产更具吸引力和挑战性，因为难以控制 C-O 活化和 C-C 偶联长链烃。在过去的几年中，在开发高效催化剂以及对其催化机理的理解方面取得了快速进展。在这篇综述中，我们对通过CO 2加氢合成 α-烯烃和芳烃的实质性进展进行了全面、权威和批判性的概述。直接和间接路线。系统地讨论了催化剂的合理制备和设计、多活性位点的邻近效应、催化剂的稳定性和失活、反应机理和反应器设计。最后，提出了先进催化剂开发中的当前挑战和潜在应用，以及未来实现碳中和的下一代 CO 2加氢技术的机会。
