NiRe Nanoparticles Supported on CeO ₂ Nanorods for the Selective Hydrogenolysis of Tetrahydrofurfuryl Alcohol to 1,5-Pentanediol

Selective hydrogenolysis of biomass-derived tetrahydrofurfuryl alcohol (THFA) into the value-added diol 1,5-pentanediol (1,5-PDO) using non-noble metal catalysts remains a significant challenge. Herein, we report an efficient NiRe bimetallic catalyst supported on morphology-controlled rod-shaped ceria (NiRe/r-CeO2), achieving a 94% yield of 1,5-PDO with an excellent selectivity of 97%. The outstanding catalytic performance is attributed to the electronic synergy between Ni and Re in the alloy phase, as well as enhanced metal–support interaction (MSI) enabled by the redox-active CeO2 nanorods. These features collectively promote alloy stabilization, active site retention, and selective C–O bond cleavage. Moreover, the catalyst exhibits robust recyclability and sustained performance over multiple cycles. This study presents a practical and sustainable catalytic strategy for biomass conversion by combining NiRe alloy synergy with morphology-enhanced metal–support interaction.
