derivatives were selectively hydrogenated to produce the desired products in high yields. In contrast to conventional nonprecious metal catalysts, nano-Co2P uniquely exhibited air stability, which enabled easy and safe handling and precluded the need for H2 pretreatment. Infrared and density functional theory studies revealed that the highly efficient hydrogenation is due to the favorable activation of the
尽管金属磷化物作为电催化剂已开始引起人们的注意,但它们在液相分子转化领域仍未得到充分利用。在本文中,我们描述了一种负载型磷化钴纳米合金(纳米Co 2 P),可作为糠醛衍生物选择性加氢的高效,可重复使用的非均相催化剂。几种糠醛衍生物的羰基部分被选择性地氢化以高产率生产所需的产物。与传统的非贵金属催化剂相比,纳米Co 2 P具有独特的空气稳定性,可轻松安全地处理,并且不需要H 2预处理。红外和密度泛函理论研究表明,高效的氢化归因于糠醛衍生物的羰基部分通过从Co d电子背向其π*轨道的背键化而得到了有利的活化。
