The catalytic hydrogenation of CO₂ with renewable H₂ is considered as one of the most practical approaches for the reduction of CO₂ and the synthesis of valuable chemicals and fuels. Among the value-added products, olefins and aromatics are highly attractive as essential industrial feedstocks. CO₂ hydrogenation to olefins and aromatics mainly undergoes a CO₂-modified Fischer-Tropsch synthesis (CO₂-FTS) route or a methanol-mediated (MeOH) route, but is often limited by low selectivity and catalyst deactivation. In this review, we first overview the reaction mechanisms and key intermediates along the CO₂-FTS and MeOH routes. For each route, we summarize the recent progress toward the catalyst development as well as the optimization of reaction conditions. We conclude the review by identifying challenges and opportunities with an emphasis on approaches for exceeding the product distribution limit, suppressing the catalyst deactivation, and improving the feasibility of low-pressure operation by continuous consumption of key intermediates.

CO ₂与可再生H ₂的催化加氢被认为是减少CO ₂和合成有价值的化学品和燃料的最实用的方法之一。在增值产品中，烯烃和芳烃作为必不可少的工业原料极具吸引力。CO ₂加氢制烯烃和芳烃主要采用CO ₂修饰的费托合成（CO ₂ -FTS）路线或甲醇介导（MeOH）路线，但往往受到选择性低和催化剂失活的限制。在这篇综述中，我们首先概述了沿 CO ₂的反应机制和关键中间体。-FTS 和 MeOH 路线。对于每条路线，我们总结了催化剂开发的最新进展以及反应条件的优化。我们通过识别挑战和机遇来结束审查，重点是超过产品分布限制、抑制催化剂失活以及通过关键中间体的持续消耗提高低压操作的可行性的方法。
