将CO ₂有效转化为碳氢化合物提供了一种方法，以取代对化石燃料的依赖，并减轻导致全球变暖的大气中多余的CO ₂的积累。因此，近年来已经进行了各种努力以将CO ₂转化为燃料和增值化学品。在这篇综述中，聚焦于通过甲醇作为中间体将CO ₂直接和间接氢化为烃。我们讨论了通过甲醇路线将CO ₂直接加氢成烃的最新方法，其中催化剂的设计，催化剂性能以及CO ₂的反应机理详细讨论氢化。作为比较，还提供了与在过渡金属和金属氧化物基催化剂上由CO ₂转化为甲醇以及从甲醇到烃相关的各种研究，并且各种沸石催化剂在富含H ₂，CO ₂和H ₂ O的环境中的性能为：讨论了甲醇转化为碳氢化合物的过程。另外，基于不同的动力学模型研究总结了对CO ₂加氢反应的性能和机理的详细分析。分析了该领域中仍然存在的挑战，并概述了与从CO ₂直接合成碳氢化合物相关的未来方向。

Recent advances in hydrogenation of CO2 into hydrocarbons via methanol intermediate over heterogeneous catalysts

The efficient conversion of CO₂ to hydrocarbons offers a way to replace the dependency on fossil fuels and mitigate the accumulation of surplus CO₂ in the atmosphere that causes global warming. Therefore, various efforts have been made in recent years to convert CO₂ to fuels and value-added chemicals. In this review, the direct and indirect hydrogenation of CO₂ to hydrocarbons via methanol as an intermediate is spotlighted. We discuss the most recent approaches in the direct hydrogenation of CO₂ into hydrocarbons via the methanol route wherein catalyst design, catalyst performance, and the reaction mechanism of CO₂ hydrogenation are discussed in detail. As a comparison, various studies related to CO₂ to methanol on transition metals and metal oxide-based catalysts and methanol to hydrocarbons are also provided, and the performance of various zeolite catalysts in H₂, CO₂, and H₂O rich environments is discussed during the conversion of methanol to hydrocarbons. In addition, a detailed analysis of the performance and mechanisms of the CO₂ hydrogenation reactions is summarized based on different kinetic modeling studies. The challenges remaining in this field are analyzed and future directions associated with direct synthesis of hydrocarbons from CO₂ are outlined.
