摘　　要：羧基碳纳米管与铜乙二胺溶液反应后于200℃焙烧制得新型载铜碳纳米管催化剂(Cu-CNTs)。考察了Cu-CNTs对乙炔氢氯化反应的催化活性。结果表明,Cu-CNTs相对于活性炭负载铜催化剂具有更好的催化活性,且更不易失活。Novel Cu-CNTs catalysts were prepared by the reaction of carboxylic carbon nanotubes with ethylenediamine solution of copper, then calcination at 200℃. The catalytic activities of Cu- CNTs in acetylene hydrochlorination were investigated. The results showed that Cu-CNTs exhibited higher initial reaction activity and slower deactivate rate than the catalyst of CuCl2 supported on the absorbent carbon.
