Ag/CNTs催化剂的载银量分析
Analysis of the Amount of Silver Supported in Ag/CNTs catalyst
【摘要】 在碳钠米管负载金属催化剂研究中 ,为了获得准确、可靠的载银数据 ,采用灼烧作预处理 ,佛尔哈德(Volhard)法测定了碳纳米管的载银量。结果表明 ,制备载银碳纳米管催化剂时所加入的银并不全部吸附在碳纳米管上 ,载银效率在 75 %左右。
【Abstract】 Calcination followed by Volhard titration was adopted for determination of the silver content in carbon nanotubes because of its precision and reliability in the study of CNTs supported catalyzers.It was shown by our results that silver was not completely adsorbed on carbon nanotubes with the adsorptive percentage of approximately 75%.
