Hydrogen can be used as an energy carrier for renewable energy to overcome the deficiency of its intrinsically intermittent supply. One of the most promising application of hydrogen energy is on-board hydrogen fuel cells. However, the lack of a safe, efficient, convenient, and low-cost storage and transportation method for hydrogen limits their application. The feasibility of mainstream hydrogen storage techniques for application in vehicles is briefly discussed in this Review. Formic acid (FA), which can reversibly be converted into hydrogen and carbon dioxide through catalysis, has significant potential for practical application. Historic developments and recent examples of homogeneous noble metal catalysts for FA dehydrogenation are covered, and the catalysts are classified based on their ligand types. The Review primarily focuses on the structure-function relationship between the ligands and their reactivity and aims to provide suggestions for designing new and efficient catalysts for H generation from FA.
氢气可作为可再生能源的能量载体，以克服其本质上间歇性供应的不足。氢能最有前景的应用之一是车载氢燃料电池。然而，缺乏安全、高效、便捷且低成本的氢气储存和运输方法限制了它们的应用。本综述简要讨论了主流储氢技术在车辆中应用的可行性。甲酸（FA）可通过催化作用可逆地转化为氢气和二氧化碳，具有重大的实际应用潜力。文中涵盖了用于甲酸脱氢的均相贵金属催化剂的历史发展和近期实例，并根据配体类型对催化剂进行了分类。本综述主要关注配体与其反应活性之间的结构 - 功能关系，旨在为设计用于从甲酸生成氢气的新型高效催化剂提供建议。
