经KOH活化处理和未经活化处理的碳纳米管分别用于负载非晶态NiP合金。以苯加氢为探针反应,研究了KOH活化处理温度和时间对碳纳米管的性质及其负载非晶态NiP催化剂活性的影响。研究结果表明:碳纳米管经KOH处理可以提高其负载非晶态NiP催化剂的催化活性,催化剂活性随活化温度升高和活化时间延长而增加。由于KOH处理改变了碳纳米管的微观结构,增加了其比表面积,所以非晶态NiP在碳纳米管上更易沉积分散,其负载的非晶态NiP合金催化剂的催化活性较高。
Carbon nanotubes activated by KOH and unactivated were respectively used to support amorphous NiP alloy. The effect of KOH activation temperature and time on the properties of CNTs and the activity of amorphous NiP supported catalysts was investigated by using hydrogenation of benzene as probe reaction. The results show that the catalytic activity of carbon nanotubes loaded with KOH can be increased, and the catalytic activity increases with the activation temperature and the activation time. Because KOH treatment changes the microstructure of CNTs and increases its specific surface area, amorphous NiP is more easily deposited and dispersed on carbon nanotubes, and the catalytic activity of amorphous NiP alloy catalysts supported by it is higher.
