Dicyclopentadiene (DCPD) resin polymerized by DCPD contains a large number of unsaturated bonds, hydrogenation plays an important role in enhancing its thermal stability and decoloring. Herein, a series of supported Cu−Ni‐Al catalysts with high distribution and large surface areas derived from direct reduction of hydrotalcite‐like compounds have been synthesized. The hydrogenation properties of supported Cu−Ni‐Al catalysts for the DCPD resin and its monomer have been investigated. The Cu1Ni3‐Al2O3 catalyst shows the highest DCPD conversion (>99%) and selectivity to tetrahydrodicyclopentadiene (THDCPD) (>98%) under mild conditions (40 °C, 2 MPa H2) compared with the corresponding catalysts prepared by impregnation and mechanically mixed method. Due to the high particle dispersion of active‐sites and the synergistic effect between metallic Cu and Ni, the optimal catalyst (Cu1Ni3‐Al2O3) also presents an expected catalytic activity in the hydrogenation of DCPD resin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations –citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
