In the context of global carbon dioxide increasing drastically, renewable energy is crucial maintain the economic growth of the world. Hydrogen has attracted considerable attention as a clean fuel, but the large-scale storage and controllable release of H₂ is still urgently needed, yet largely not yet accomplished. Through the reactions of CO₂ hydrogenation to formic acid (FA) and FA dehydrogenation to hydrogen, a “carbon neutral” sustainable hydrogen storage system can be constructed. With advantages of excellent recyclability and facile separation for heterogeneous catalysis, developing efficient heterogeneous catalysts for hydrogen storage based on FA is the primary focus of this review, mainly involving metal catalysts from nanoscale to single-atom scale. Firstly, the effects of metal size on the catalytic activities are highlighted in detail. Additionally, special attention is paid to the relevant structure–activity relationships of various supported catalysts and the mechanistic insights, which can provide a theoretical foundation for rational catalyst design. This review brings new and systemic insights into innovative and efficient heterogeneous catalysts design and applications for the ultimate FA-based sustainable hydrogen storage system with a closed carbon loop.

基于甲酸的二氧化碳介导储氢技术的多相催化

在全球二氧化碳急剧增加的背景下，可再生能源是维持世界经济增长的关键。_{氢气作为一种清洁燃料备受关注，但H 2}的大规模储存和可控释放仍是亟待解决的问题，但很大程度上尚未实现。通过CO _2的反应加氢制甲酸（FA）和脱氢制氢，可构建“碳中和”可持续储氢系统。具有优异的可回收性和多相催化分离容易的优点，开发基于FA的高效多相储氢催化剂是本综述的主要重点，主要涉及从纳米级到单原子级的金属催化剂。首先，详细强调了金属尺寸对催化活性的影响。此外，还特别关注了各种负载型催化剂的相关构效关系和机理见解，可为合理的催化剂设计提供理论基础。
