Preparation of NiCoB/SiO2 nanoalloy catalysts and their catalytic hydrogenation performance

摘要

The nanoalloy NiCoB and NiCoB/SiO2 catalysts were prepared by an incipient impregnation-chemical reduction method with NaBH4. They were characterized and examined for their catalysis in the hydrogenation of furfural to furfural alcohol. NiCoB and NiCoB/SiO2 catalysts were characterized by XRD as amorphous structure. The amorphous NiCoB/SiO2 catalyst was active in the hydrogenation of furfural, and it was significantly more active than NiB, CoB and NiCoB.
