In this work, an effective and versatile modification approach of palladium (Pd)/nitrogen doped carbon by iron series element for the semihydrogenation of phenylacetylene is presented. Pd and iron series element M (M=Fe, Co or Ni) particles were co‐reduced and supported on nitrogen‐doped activated carbon (Pd−M/NC). Experimental results showed that the Pd−M/NC exhibited relatively good catalytic performance when the Pd/M content mass ratio was approximately 1 : 1. The selectivity of styrene could be maintained at relatively good levels even with the prolongation of reaction time. The good catalytic effect of the Pd−M/NC may be attributed to the incorporation of iron series element species. The catalysts had been characterized in detail and contrastive study was made to validate the modification effect. The catalyst could maintain its catalytic activity and selectivity in the recycle process. This work may show industrial application potentiality and developing directions in selective hydrogenation process.
