Abstract: sThe development of highly efficient catalysts for the hydrogenation of dicyclopentadiene (DCPD) remains a critical challenge. In this study, we designed a series of bimetallic Ce-Ni metal-organic framework (MOF)-derived nanocatalysts by precisely tuning the Ce/Ni ratio and calcination temperatures. The optimized catalyst, Ni-CeO2@C-400 °C, featuring highly dispersed carbon-coated Ni nanoparticles, achieved complete hydrogenation of DCPD to tetrahydrodicyclopentadiene (THDCPD) with 100% conversion and nearly 100% selectivity within 2 hours under 100 °C and 2 MPa. The porous carbon framework significantly facilitate the diffusion and accessibility of DCPD molecules,combined with Ce species reconstructs the electronic structure of Ni active centers through electronic interactions,synergistically enhance the hydrogenation efficiency. Furthermore, the catalyst demonstrated good structural stability. This work not only provides a robust strategy for the rational design of bimetallic MOF-derived catalysts but also highlights their potential for practical applications in industrial hydrogenation processes.
