Selective ring-opening hydrogenolysis of the furan ring is the key to the efficient conversion of furfuryl alc. (FFA) to high-value pentanediol. In this work, highly dispersed Cu@MgO-La2O3 was designed and synthesized with a core-shell structure, and bifunctional metal and alk. sites for the direct hydrolysis of FFA (94.9% conversion) to 1,2-pentanediol (1,2-PeD, with 67.1% selectivity) and 1,5-pentanediol (1,5-PeD, with 18.8% selectivity). Multiple characterization results indicated that at an Mg/La ratio of 1.9, the outer surface contained distributed La2O3-MgO species with uniformly dispersed Cu0 nanoparticles, and the inner layer of the catalyst possessed MgO, while some Cu0 were distributed at the La2O3 and MgO interface. The addition of MgO increased the sp. surface area of the outer layer, improving the dispersion of Cu and facilitating the formation of Cu0. In-situ FTIR experiments showed that FFA was adsorbed on the La2O3 alk. site of the carrier through the O atoms of the furan ring and CH2OH, which induced ring-opening to generate enol intermediates, which further hydrogenated to 1,2-PeD and 1,5-PeD over the Cu0 nanoparticles. Thus, this new core-shell structure combining with metal and alk. sites provides new insight for developing effective and selective hydrogenolysis catalysts.
