摘要

通过高温脉冲成功制备了嵌入 Mo2C 的钯纳米粒子，该纳米粒子可高效地将炔烃半氢化为烯烃，其中嵌入的钯位点具有适当的炔烃吸附性，但抑制了烯烃吸附性，因此在各种炔烃的氢化过程中表现出高的活性和良好的烯烃选择性。

Semi-hydrogenation of alkynes to alkenes over Pd nanoparticles embedded in Mo₂C prepared from a high-temperature pulse.

Pd nanoparticles embedded in Mo₂C were successfully prepared from a high-temperature pulse, and are efficient for semi-hydrogenation of alkynes to alkenes, where the embedded Pd sites possessed appropriate alkyne adsorption but suppressed alkene adsorption, thus exhibiting both high activities and good alkene selectivities in the hydrogenation of various alkynes.
