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.

高温脉冲制备的嵌入 Mo2C 中的 Pd 纳米颗粒上炔烃半氢化为烯烃


嵌入 Mo₂C 的 Pd 纳米颗粒通过高温脉冲成功制备，并且有效地将炔烃半氢化为烯烃，其中嵌入的 Pd 位点具有适当的炔烃吸附但抑制了烯烃吸附，因此在各种炔烃的加氢中表现出高活性和良好的烯烃选择性。
