摘　　要：采用表面活性剂为模板制备了具有一维结构的Co-B非晶态纳米线,用于糠醛液相选择性加氢制取糠醇。纳米线形貌较均一,XRD测试结果显示其非晶态结构。相比于Co-B纳米颗粒来说,Co-B纳米线具有更高的比表面积以及优良的催化活性和糠醇选择性。在循环测试中,一维的Co-B纳米线具有更高的热稳定性。One dimensional Co-B amorphous nanowires were prepared by using surfactant as template which were used for selective hydrogenation of furfural to furfuryl alcohol in liquid phase.Co-B nanowires were uniform and the results of XRD showed that their structure was amorphous.Compared with Co-B nanoparticles,Co-B nanowires had higher specific surface area,better catalytic activity and selectivity to furfuryl alcohol.In the cyclic test,the Co-B nanowires with one-dimensional structure had higher thermal stability.
