摘要

Catalytic transfer hydrogenation (CTH) of α,β-unsaturated aldehydes to α,β-unsaturated alcohols over metal oxide catalysts is of potential for industrial application. Herein, we have developed a Ni/f-Al2O3 catalyst comprising atomically dispersed Niδ+ (2 < δ < 3) species on porous leaf-like Al2O3, over which a > 97% yield of furfuryl alcohol (FOL) from CTH of furfural (FFR) is obtained with a turnover frequency (TOF) of 216 h− 1. Most importantly, the catalyst can be recycled at least 6 times without obvious loss of activity. Its superior catalytic performance can be attributed to the abundant and stable Niδ+-type acid-base pairs on the surface of Ni/f-Al2O3.
