A Co-promoted Ni-B amorphous nanoalloy catalyst for liquid phase hydrogenation of furfural to furfural alcohol

摘要

The Co-promoted Ni-B amorphous nanoalloy catalysts were prepared by the chemical reduction of the aqueous solution containing nickel acetate and cobalt acetate with NaBUt at room temperature and characterized by BET,XRD and DSC. They were used as catalysts for the liquid phase hydrogenation of furfural to furfural alcohol in alcohol at 353 K under 2.0 MPa of hydrogen. Ni-Co-B catalyst was characterized by XRD as amorphous structure. It was active in the hydrogenation of furfural,and it was significantly more active than Ni-B and Co-B. The optimal Co/(Co+Ni) mole ratio in Ni-Co-B was 0.5.
