The conversion of syngas into valuable fuels and chemicals has been studied for a long period and is always influenced by water products such as the water-gas shift side reaction to form CO₂ and competitive adsorption with reactants, yielding reduced activity. Recently, it has been reported that hydrophobization of the catalysts to accelerate water desorption could efficiently overcome such a limitation and improve catalytic performance in the syngas conversion. In this review, we focus on catalytic performances in the conversion of syngas to methane, dimethyl ether, and olefins by controlling the catalyst hydrophobicity. In addition, we also discuss the chemical modification for hydrophobization of the catalysts. Furthermore, the hydrophobic promoters are specifically mentioned because they could improve syngas conversion by physically mixing with the catalyst without chemical alterations to the catalyst surface. Finally, the concerns and challenges in this field are outlined, and a realistic outlook is suggested for precisely regulating the wettability of the catalysts. We hope that this review will be helpful for designing highly efficient heterogeneous catalysts in the future.

_{合成气向有价值的燃料和化学品的转化已经被研究了很长一段时间，并且总是受到水产物的影响，例如形成CO 2}的水煤气变换副反应以及与反应物的竞争吸附，导致活性降低。最近，有报道称，催化剂的疏水化加速水解吸可以有效克服这一限制并提高合成气转化中的催化性能。在这篇综述中，我们重点关注通过控制催化剂疏水性将合成气转化为甲烷、二甲醚和烯烃的催化性能。此外，我们还讨论了催化剂疏水化的化学修饰。此外，特别提到疏水性促进剂，因为它们可以通过与催化剂物理混合来提高合成气转化率，而不会对催化剂表面进行化学改变。最后，概述了该领域的担忧和挑战，催化剂的润湿性。我们希望这篇综述对未来设计高效的多相催化剂有所帮助。
