Hydrogen is recognized as an ideal substitute for conventional energy sources due to its exceptional merits. However, the lack of inexpensive and efficient hydrogen storage approaches is the main obstacle for the “Hydrogen Economy”. Liquid organic hydrogen carriers (LOHCs) are attractive due to the decoupling of energy generation and usage in both space and time. Herein, we surveyed the recent advances of heterogeneous catalysts for different LOHCs, including methanol, ethanol, formic acid, formate salts, toluene, dibenzyl-toluene, and heterocycles. This review categorizes the catalysts by other metal species and discusses their catalytic mechanisms on hydrogenation and dehydrogenation. The challenges associated with the development of nanoscale heterogeneous catalysts and the possible solutions are also discussed. Finally, the future research directions for developing next-generation heterogeneous catalysts are outlined.

由于其特殊的优点，氢被公认为传统能源的理想替代品。然而，缺乏廉价高效的储氢方法是“氢经济”的主要障碍。液态有机氢载体（LOHC）具有吸引力，这是因为能量的产生和使用在空间和时间上都脱钩了。在此，我们调查了用于不同 LOHC 的多相催化剂的最新进展，包括甲醇、乙醇、甲酸、甲酸盐、甲苯、二苄基甲苯和杂环。本综述将催化剂按其他金属种类分类，并讨论了它们对加氢和脱氢的催化机制。还讨论了与纳米级多相催化剂开发相关的挑战和可能的解决方案。最后，
