摘要 以活性炭为载体,制备了Pd/C,Pd Co/C催化剂.活性评价结果表明,Pd Co/C催化剂显示出良好的催化性能,反应4h后,葡萄糖的转化率达98.8%,较Pd/C催化剂的活性有显著的提高.BET,XRD表征结果也表明,Co的添加及焙烧过程,使载体由无定形结构转变为晶型结构,且比表面积和微孔容积均有所增加,既提高了Pd的表面分散度,又增大了Pd在催化剂表面的裸露程度,从而使Pd Co/C催化剂表现出良好的催化性能. With carbon acted as carrying agents, both Pd/C and Pd Co/C as catalyst were made. The results to assess its catalystic performace show: Pd Co/C is much more better than Pd/C, it presents good catalytic property, after four hours reaction, the conversion of glucose reaches 98.8%. Also the characterization of BET and XRD exhibits: after Co is added, the carrying agents is converted from amorphous state into crystalline, its stecific surface area and pore volume are added, improving the disperse and exposure of Pd is the secret.
