Nickel-tungsten carbide catalysts convert furfural to high value products in a liquid phase catalytic reaction. The product distribution depends on the solvent and the Ni-W-ratio of the catalyst. In isopropyl alcohol a combination of Ni and W C enables the opening of the furan ring to yield 1,2-pentanediol. Nickel accelerates the tungsten oxide reduction in the tungsten carbide catalyst synthesis and facilitates the carbon insertion. Nickel modified tungsten carbide is a promising, noble metal-free catalyst system for the upgrading of furfural based renewable resources. Its preparation is facilitated compared to unmodified tungsten carbide catalysts.
碳化镍 - 碳化钨催化剂在液相催化反应中将糠醛转化为高价值产物。产物分布取决于溶剂和催化剂的镍钨比。在异丙醇中，镍和碳化钨的组合能使呋喃环开环生成1,2 - 戊二醇。在碳化钨催化剂合成过程中，镍加速氧化钨的还原并促进碳插入。镍改性碳化钨是一种用于升级基于糠醛的可再生资源的有前景的无贵金属催化剂体系。与未改性的碳化钨催化剂相比，其制备更容易。
