1、Pt/C催化剂结构与类型是什么?
这个就应该是Pt颗粒分散在活性炭的表面,如果是石墨烯和碳纳米管载体,可能还有不同的形貌!欢迎参考:
石墨烯上负载的Pt
Selective hydrogenation of cinnamaldehyde over reduced graphene oxide supported Pt catalyst
Catalysis Communications, Volume 41, 5 November 2013, Pages 101-105
Platinum supported on reduced graphene oxide as a catalyst for hydrogenation of nitroarenes
Carbon, Volume 50, Issue 2, February 2012, Pages 586-596
活性炭上负载的Pt
Selective oxidation of glycerol in a base-free aqueous solution over different sized Pt catalysts
Catalysis Communications, Volume 10, Issue 12, 25 June 2009, Pages 1586-1590
纳米碳管上负载的Pt
Selective oxidation of glycerol with oxygen in a base-free aqueous solution over MWNTs supported Pt catalysts
Applied Catalysis B: Environmental, Volume 106, Issues 3–4, 11 August 2011, Pages 423-432
2、用Pt/C来使硝基苯催化加氢合成对氨基苯酚,针对这个反应,Pt/C催化剂的反应作用机理是什么?
Pt/C上主要是氢的吸附与活化,还有部分载体可以吸附底物。
硝基苯催化加氢合成对氨基苯的反应机理可以参考:
Platinum supported on reduced graphene oxide as a catalyst for hydrogenation of nitroarenes
Carbon, Volume 50, Issue 2, February 2012, Pages 586-596 |
