Bimetallic copper- and nickel-rich Cu-Ni phyllosilicate catalysts for the liquid phase selective hydrogenation of furfural to furfuryl alcohol.

ABSTRACT: Bimetallic Cu-Ni phyllosilicates (Cu-NiPS) with various Ni/Cu ratios (5 : 15, 10 : 10, 15 : 5 wt%) were synthesized using ammonia evaporation hydrothermal method to obtain copper-rich or nickel-rich Cu-Ni alloys. These catalysts were evaluated for the selective hydrogenation of furfural (FF) to furfuryl alcohol (FA) in the liquid phase under relatively mild conditions (100 °C, 20 bar H₂). The bimetallic Cu-NiPS catalysts exhibited excellent dispersion of the Ni-Cu alloy with average particle sizes ranging from 3.8 to 4.8 nm and demonstrated significantly enhanced catalytic performance over the monometallic nickel phyllosilicate (20% NiPS). The copper-rich Ni-Cu alloy (15% Cu-5% NiPS) exhibited the highest FF conversion efficiency (88%) and FA selectivity (90%). This superior per
