CO hydrogenation to hydrocarbons is a promising way of making waste to wealth and energy storage, which also solves the environmental and energy issues caused by CO emissions. Much efforts and research are aimed at the conversion of CO hydrogenation to various value-added hydrocarbons, such as CH, lower olefins, gasoline, or long-chain hydrocarbons catalyzed by different catalysts with various mechanisms. This review provides an overview of advances in CO hydrogenation to hydrocarbons that have been achieved recently in terms of catalyst design, catalytic performance and reaction mechanism from both experiments and density functional theory calculations. In addition, the factors influencing the performance of catalysts and the first C-C coupling mechanism through different routes are also revealed. The fundamental factor for product selectivity is the surface H/C ratio adjusted by active metals, supports and promoters. Furthermore, the technical and application challenges of CO conversion into useful fuels/chemicals are also summarized. To meet these challenges, future research directions are proposed in this review.
将一氧化碳加氢转化为碳氢化合物是一种变废为宝和储能的很有前景的方法，这也解决了由一氧化碳排放引起的环境和能源问题。许多努力和研究都致力于将一氧化碳加氢转化为各种增值碳氢化合物，例如由具有不同机理的不同催化剂催化生成甲烷、低级烯烃、汽油或长链碳氢化合物。本综述从实验和密度泛函理论计算两方面，概述了近期在一氧化碳加氢制碳氢化合物方面在催化剂设计、催化性能和反应机理等方面所取得的进展。此外，还揭示了影响催化剂性能的因素以及通过不同途径的首个碳-碳偶联机理。产物选择性的基本因素是由活性金属、载体和促进剂调节的表面氢/碳比。此外，还总结了将一氧化碳转化为有用燃料/化学品的技术和应用挑战。为应对这些挑战，本综述提出了未来的研究方向。
