Abstract
Designing efficient and facile recoverable catalysts is desired for sustainable biomass valorization. This work reports the one-pot synthesis of a novel magnetic Fe(NiFe)O4–SiO2 nanocatalyst for hydrogenation of biomass-derived furfural into valuable furfuryl alcohol. Various techniques were used to systematically analyze the physicochemical properties of the Fe(NiFe)O4–SiO2 nanocatalyst. Vibrating sample magnetometer analysis reveals low coercivity of Fe(NiFe)O4–SiO2 (6.991 G) compared with that of Fe3O4–SiO2 (27.323 G), which is attributed to highly dispersed Ni species in the Fe(NiFe)O4–SiO2 catalyst. HRTEM images indicated the nanosized nature of the Fe(NiFe)O4–SiO2 catalyst with an average diameter of ∼14.32 nm. The Fe(NiFe)O4–SiO2 catalyst showed a superior BET surface area (259 m2/g), which is due to the formation of nanosized particles. The magnetic Fe(NiFe)O4–SiO2 nanocatalyst shows a remarkable performance with 94.3 and 93.5% conversions of furfural and ∼100% selectivity of furfuryl alcohol at 9...
