纳米碳材料负载铂催化剂在环己烷脱氢反应中的催化性能研究

制备了纳米碳材料负载铂的催化剂，通过N₂吸附、TEM、XRD技术分别对载体的BET比表面积和催化剂结构、形貌和粒径大小进行了表征。考察了不同催化剂在环己烷脱氢反应中的催化性能以及温度对纳米碳颗粒负载铂催化剂活性的影响。结果表明，锚定在不同碳载体上的铂有较好的分散性，粒径较小，粒度分布范围较窄并且具有相同的晶型结构。孔状纳米碳颗粒负载铂催化剂的活性高于碳纳米管和高比表面的活性炭负载铂催化剂，并且在低温条件下已经显示了较高的活性，尤其是中空碳颗粒负载铂催化剂在环己烷脱氢反应中显示了好的活性和稳定性。

Cyclohexane dehydrogenation over the platinum catalysts supported on carbon nanomaterials

Platinum catalysts supported on carbon nanoparticles and other carbon materials were prepared.Their surface area,structure,morphology and particle size were characterized by nitrogen sorption,TEM and XRD.The activity of various catalysts for cyclohexane dehydrogenation was investigated under different reaction temperatures.The results showed that Pt particles were well dispersed on the surface of nanoparticles and the size distribution was in a narrow range;the Pt catalyst supported on the hollow carbon nan...
