钯吸收氢是热力学的。在钯催化剂上的氢化反应的工业条件下，钯颗粒应该作为氢化钯-PdHx（x > 0.6）起作用，这表明在氢化反应中吸收的氢的加入。本文在综述钯表面吸放氢过程的热力学、动力学和微观机理的基础上，简要介绍了近年来钯表面吸附氢对烯烃加氢反应的影响。
Palladium absorbs hydrogen exothermically. Under the industrial conditions for hydrogenation reactions over palladium catalysts, palladium particles should be working as palladium hydride α'-PdHx (x > 0.6), which suggests the enrollment of absorbed hydrogen in the hydrogenation reaction. In this article, after the energetics, kinetics, and microscopic mechanism of the hydrogen absorption and release processes on palladium surface is reviewed, the recent research on the role of absorbed hydrogen on the alkene hydrogenation reaction on palladium is briefed.
