Other AbstractCatalysts of Ni4.63Cu1Al1.82Fe0.79,Ni4.65Cu1Co0.92Al1.96Fe0.74and Ni4.59Cu1Mg1.58Al1.96Fe0.70were prepared by a co-precipitation method with active sites of nickel as hydrotalcite precursor.The hydrogenation of xylose into xylitol by the catalysts was carried out under hydrogen atmosphere,and the products were determined by HPLC.The properties of the catalysts were characterized by XRD,N2adsorption-desorption,NH3-TPD,and H2-TPR.The potential relationship between the surface properties of the catalysts and their catalytic activity was investigated.With the doping of Co and Mg,the surface area,adsorption capacity,and hydrogen consumption of the catalysts increased,while the reduction temperature decreased.The catalytic activity of Ni4.65Cu1Co0.92Al1.96Fe0.74and Ni4.59Cu1Mg1.58Al1.96Fe0.70was higher than Ni4.63Cu1Al1.82Fe0.79,the conversion rate of xylose increased from90.5%to95%and95.7%respectively.
