摘　　要：以CNTs为载体制备的Pd-Fe双金属非晶态催化剂用于氯代硝基苯的加氢脱卤反应。对该催化剂在超临界CO2中的催化活性进行了评价。实验结果证明,该催化剂在实验条件下具有较好的加氢脱氯活性。用XRD和SEM技术对该催化剂的结构和形貌进行了表征,并初步探讨了该催化剂的加氢脱卤机理。Pd- Fe -B bimetallic amorphous catalyst supported on carbon nanatbes（CNTs） is applied in the hydrodechlorination reaction of chloronitrobenzene. Catalytic activity of the catalyst is evaluated under supercritical CO2 （SCCO2）. Experiments results demonstrate that the catalyst has better catalytic activity in the reaction of hydrodechlorination of chloronitrobenzene under SCCO2. The structure and morphology of the catalyst are characterized by XRD and SEM technology, and preliminary discussion on mechanism of hydrodechlorination of chloronitrobenzene is made based on the characteriztions.
