摘要	Furfuryl Alcohol (FOL) from the catalytic hydrogenation of furfural represented a promising intermediate for industrial application. However, the high selectively of FOL in mild temperature was limited due to the over hydrogenation. Here, we synthesized the novel ultra-dilute high-entropy alloys (HEAs) with multiple metal sites and core-shell structure for boosting the selectivity of furfural hydrogenation to furfuryl alcohol. The results showed that the furfural was converted to FOL with the conversion of 87.32% and selectivity of 100% at 90 degrees C over ultra-dilute HEA (NiCoCuZnFe/C-800). The catalyst had redistribution of electrons between Cu (2.00) and atomically dispersed Zn (1.65) due to the different electronegativity. The electron-rich Cu repelled the furan ring and prevented the over hydrogenation, while the atomically dispersed Zn presented the strongest -CHO adsorption performance. Moreover, the core-shell structure enhanced the stability of the catalysts during hy-drogenation reaction and the porous carbon shell improved the transferring of furfural and electronic.
