Developing the highly active Pd catalyst via facile synthesis technique for alkenes hydrogenation is a long-term goal to pursuit. Here, Pd catalyst with phosphor-doped g-C₃N₄ as support was fabricated by calcination and impregnation technique. XRD and XPS indicated that phosphor was doped into the framework of g-C₃N₄,resulting in the highly dispersed Pd loaded thereon. The resultant Pd catalyst exhibited an unprecedentedly high activity for styrene hydrogenation of 856.89 mmol_Styrene·min⁻¹·g_Pd⁻¹ and TOF value of 18,974 h⁻¹ attributed to the enhanced Pd dispersion, more Pd⁰ species and the intrinsic advantages of the support. This work provides a new avenue for the fabrication of highly effective Pd catalyst over alkenes hydrogenation.

通过简便的合成技术开发高活性钯催化剂进行烯烃加氢是一个长期的目标。在此，通过煅烧和浸渍技术制备了以掺杂磷的gC ₃ N ₄为载体的Pd催化剂。XRD和XPS表明荧光粉被掺入了gC ₃ N ₄的骨架中，导致了Pd的高度分散。所得的Pd催化剂对苯乙烯的氢化反应表现出空前的高活性，为856.89 mmol_苯乙烯·min ^-1 ·g _Pd ^-1，TOF值为18,974 h ^-1，这归因于Pd分散性的提高，Pd ⁰更多种类和内在优势的支持。这项工作为通过烯烃加氢制备高效Pd催化剂提供了一条新途径。
