Abstract The catalytic response of Ni on Al 2 O 3 obtained from Ni–Al layered double hydroxides was studied for the liquid‐phase hydrogenation hydroxymethyl furfural to tetrahydrofuran‐2,5‐diyldimethanol (THFDM) in water. successive calcination and reduction precursors caused removal interlayer hydroxyl carbonate groups 2+ 0 . Four reduced mixed oxide catalysts were obtained, consisting different amount metal contents (47–68 wt %) an Al‐rich amorphous component. activity linked content...
