摘 要:通过化学还原法合成了平均粒径为 2. 3 nm 的铂胶体,然后将其负载在碳纳米管
(CNT)上,制备了碳纳米管负载的铂纳米颗粒催化剂(Pt/CNT)。Pt/CNT 催化剂可以在温
和的条件下催化氯苯几乎完全脱氯,表现出了良好的脱氯性能。探究了醇类溶剂、极性非质
子溶剂以及不同直径 CNT 载体对 Pt/CNT 催化加氢脱氯反应活性的影响。同时,Pt/CNT 催
化剂还表现出了良好的选择性和稳定性。

Abstract:Colloidal platinum nanoparticles with an average particle size of 2. 3 nm were synthe sized by chemical reduction, and then supported on carbon nanotubes (CNT) to prepare carbon nanotube-supported platinum nanoparticles catalysts (Pt/CNT). The Pt/CNT catalyst showed superior catalytic hydrodechlorination performance that chlorobenzene was completely hydrodechlorinated under mild conditions. The effects of alcohol solvents, polar aprotic sol vents and CNT carriers with different diameters on the activity of Pt/CNT catalytic hydrode
chlorination were investigated. The Pt/CNT catalysts showed stable selectivity and activity with recycling.
Key words:chlorobenzene; hydrodechlorination; carbon nanotube; platinum nanoparticle catalyst; solvent effect
