Oxygen Vacancy-Induced Interfacial Lanthanum Hydride and Hydroxide Bifunctional Sites for Selective Hydrogenolysis of Furanic Compounds to Alkyl Diols

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(13), P. 10009 - 10021

Published: June 19, 2024

Selective hydrogenolysis of C–O bonds in biomass-derived oxygenated molecules is great significance for the conversion biomass to chemicals and fuels, especially inert C–O–C tetrahydrofuran rings. However, lack precise active sites results low activity this reaction. In work, metal–support interfacial structure Ni–La2O3 catalyst was well-controlled by reducing LaNiO3 perovskite at different temperatures. During reduction, exsolution segregation Ni led formation metallic nanoparticles oxygen-vacant Ni2+-Ov-La3+ sites. Hydrogen spillover from interface promoted situ generation La–OH species under reaction conditions. At same time, oxygen vacancies can accommodate spilled H, inducing La–H species. The hydroxyl group tetrahydrofurfuryl alcohol (THFA) interacted with through a metal alkoxide intermediate, which subsequently hydrogenolyzed produce 1,5-pentanediol (1,5-PeD). intimate bifunctional on have strong synergistic effect, endowing high THFA activity. proposed assisted bond provides an idea design efficient hydrodeoxygenation catalysts upgrading.
