As a state-of-the-art resource for in situ hydrogen supply, formic acid has recently attracted considerable attention due to its advantages of high hydrogen content, low toxicity, and easy storage and transportation. However, generating hydrogen from formic acid in a controlled manner under mild conditions is still challenging. The stability of formic acid dehydrogenation (FAD) catalysts and CO selectivity require further investigation. With this in mind, recent advances in heterogeneous catalysts, homogeneous catalysts, and carbon-based supports are summarized. After that, a perspective on catalyst design (the size-sensitivity effect, core–shell catalysts, single-atom catalysts, and metal–organic framework-derived catalysts), mechanism clarification, and microchannel reactor construction is proposed for effectively propelling the development of FAD. This perspective aims at not only providing innovative ideas for fundamental research in FAD, but also promoting the applications of in situ hydrogen supply obtained from formic acid.

热催化甲酸脱氢：最新进展和新趋势

作为最先进的原位资源供氢方面，甲酸由于具有含氢量高、毒性低、易贮运等优点，近来备受关注。然而，在温和条件下以受控方式从甲酸中产生氢气仍然具有挑战性。甲酸脱氢 (FAD) 催化剂的稳定性和 CO 选择性需要进一步研究。考虑到这一点，总结了多相催化剂、均相催化剂和碳基载体的最新进展。之后，提出了催化剂设计（尺寸敏感性效应、核-壳催化剂、单原子催化剂和金属-有机骨架衍生催化剂）、机理阐明和微通道反应器构建的观点，以有效推动催化剂的发展。时尚。从甲酸获得的原位氢气供应。
