含氧基团在活性碳纤维表面的存在及对NO的还原

Evidence for the Existence of Surface Oxides on Activated Carbon Fibers and Its Effect on Reduction Reaction of NO

利用程序升温还原 (TPR)、程序升温脱附 (TPD)等试验方法 ,证明了未改性、硝酸基、铜基的活性碳纤维(ACF)上存在含氧基团。在微型反应器中对这些 ACF与 NO的反应产物进行了定量测定 ,发现 NO脱除与 ACF含氧量和表面含氧基团存在及分布有关。还考察了

By means of TPR,TPD,the existence of oxygen containing groups on various kinds of ACF (including HNO 3 modified and Cu modified ACF) were proved.The reaction of NO with various ACF was carried in a micro reactor system and the products of this reaction were analyzed.The existence of oxygen containing groups on ACF affects the NO removal reaction seriously.The effect of NO on this reaction was studied,too.
