Abstract

Graphical abstract: Highlights: Uniformly porous SiO2 nanosphere-supported PtCuCo alloy catalysts are prepared. PtCuCo/SiO2 shows 95.4% selectivity to furfuryl alcohol (97.9% furfural conversion) PtCuCo/SiO2 exhibits higher catalytic activity and selectivity than other as-obtained catalysts. Electronic synergy effect in PtCuCo/SiO2 results in its high catalytic performance. Abstract: Furfural is one of the most important lignocellulose derivatives in biomass. Its conversion to furfural alcohol (FA) is a great significance for value-added green chemicals. Here, we show that the hydrogenation of furfural over a SiO2 nanosphere-supported PtCuCo alloy catalyst (PtCuCo/SiO2 ), which exhibits excellent conversion to FA, up to 97.9%, with a selectivity to 95.4%. The superior activity is attributed to the formation of a PtCuCo alloy (Pt-Cu-Co sites) over the high-surface-area mesoporous silica. Structural and chemical characterizations indicate the formation of the PtCuCo alloy nanoparticles (NPs) in the catalyst is highly beneficial to the hydrogenolysis of furfural to produce intermediates, which are further hydrogenated to produce FA, with remarkable selectivity and efficiency.
