Ozonation of Fibrous Carbon Materials and the Effect of Molybdenum Compounds on This Process

摘要

The low-temperature oxidative modification of fibrous carbon with ozone affords fibrous carbon materials (FCMs) with a high acid group content (up to 5.7 mg-equiv/g). As the ozonation time is extended, the acid groups build up, the benzene vapor and metal ion (Ni~(2+) and Cu~(2+)) sorption activities increase, and the specific surface area of FCM decreases. Molybdenum oxides reduce the efficiency of the interaction between FCM and ozone.
