We describe herein that the quasi-one-dimensional confinement effect of functionalized nanoporous supports is particularly advantageous for boosting formic acid (FA) dehydrogenation efficiency over palladium nanoparticles (NPs). Benefiting from their unique structural merits that lead to significant lowering of the entropic barrier for FA activation, the Pd NPs interiorly located on the amino-modified MCM-41 offer the promise of more than an order of magnitude speedup of the initial activity in H₂ production from FA over their exterior analogs. Under mild and additive-free conditions, ultrafine Pd NPs confined in amino-modified MCM-41 channels exhibit an initial turnover frequency as high as 46,677 h⁻¹ and a turnover number up to 1,060,000 at 60°C. In conjunction with the enhancement and robust performance for efficient regeneration of FA via CO₂ hydrogenation, the presented approach greatly contributes to the development of FA-based hydrogen storage and related technologies as viable means of enabling sustainable future energy prospects.

我们在本文中描述了功能化的纳米多孔载体的准一维限制作用对于提高甲酸（FA）的脱氢效率优于钯纳米颗粒（NPs）特别有利。得益于其独特的结构优势，该结构优势大大降低了FA活化的熵屏障，位于氨基修饰的MCM-41上的Pd NPs有望使H ₂中的初始活性加快一个数量级以上。FA通过其外部类似物进行生产。在温和且无添加剂的条件下，限制在氨基修饰的MCM-41通道中的超细Pd NP的初始转换频率高达46,677 h ^-1在60°C下的营业额高达1,060,000。结合通过CO ₂加氢有效再生FA的增强功能和强大性能，该方法极大地促进了基于FA的储氢技术和相关技术的发展，成为实现可持续未来能源前景的可行手段。
