摘要： One-pot conversion paths of C5 substrates to 1,5-pentanediol (1,5-PDO) will allow efficient production of polyesters, polyurethanes and fungicides. Although efficient conversion of tetrahydrofurfuryl alcohol (THFA) to 1,5-PDO has been achieved, selective production of 1,5-PDO from hemicellulose-derived furfural (FF) or from furfuryl alcohol (FFA) in high yields has yet to be reported. Herein, direct conversion of FFA to 1,5-PDO was achieved in yields as high as 72.5 % over NiLa@ZrO2 catalyst. The combination of La species with ZrO2 effectively increased the abundance of basic sites and oxygen vacancies on the catalyst and the close proximity of Ni0 and basic sites facilitated both homolytic and heterolytic dissociation of H2 molecules. In the mechanistic pathway, the C=C bond of FFA was first hydrogenated by homolytic H atoms of H2 molecules to form tetrahydrofurfuryl alcohol and then heterolytic H delta- and H delta+ species acted to cleave the C2-O bond in tetrahydrofurfuryl alcohol activated by basic sites and oxygen vacancies of the catalyst to afford 1,5-PDO. The results of this work demonstrate the possibility of directly and efficiently upgrading FFA to 1,5-PDO using non-precious metal catalysts.
