摘要：

Coupling of CO2 with biomass-derived molecules into degradable plastic monomer provides a promising strategy to address the increasing problems of carbon recycle and carbon neutrality. Herein, we develop a sustainable route to produce 6-hydroxycaproate (6-HMC) by coupling photocatalytic carboxylation of biomass-derived furfuryl alcohol with CO2 to 2-furanacetic acid (FA), and the thermocatalytic hydrogenolysis of methyl 2-tetrahydrofuranyl acetate (MTFA) derived from FA, wherein Pd/CeO2 exhibit the highest productivity of 6-HMC (505 mmol(6-HMC) mmol(metal)(-1) h(-1)), much higher than its counterparts of precious- and non-precious-metal catalysts. Moreover, Pd/CeO2 also presents good stability for 6 recycles without remarkable decrease in 6-HMC yield. Systematic experiments and computational studies suggest that higher concentration of oxygen vacancies and strong metal-support interactions account for enhanced catalytic performance of Pd/CeO2. The work employs CO2 and lignocellulosic-derived platform molecule as feedstocks to produce valuable degradable plastic monomer, providing a promising route to access pure-CO2 originated high-carbon oxygen-containing compounds.
