A remarkable enhancement of catalytic activity for KBH4 treating the carbothermal reduced Ni/AC catalyst in glycerol hydrogenolysis

It reported a novel procedure for preparing Ni/AC catalyst for the glycerol hydrogenolysis, which involved carbothermal reduction of supported nickel nitrate and further treatment with KBH4. The activity of the as-prepared catalyst was remarkably enhanced compared with KBH4, H2 or carbothermal reduced Ni/AC catalyst. The Ni particles and the variation of oxygen-containing surface groups (OSGs) were studied by XRD, TEM, FT–IR, He-TPD and NH3-TPD techniques. The high dispersed Ni and the acidity generated by the OSGs have the synergy effect on the activity of glycerol hydrogenolysis.
