Аннотация доклада:
The carbon nanomatherials: nanotubes (CNTs), nanodiamond (ND) and nanoflakes (CNF) were employed as catalysts in the 1,2-dichloroethane dechlorination and the C2-C4-alcohols conversion. Catalytic activity in 1.2-dichloroethane conversion was exhibited only by ND, and the selectivity to ethylene was almost 100%. The key role in catalysis plays a "diamond" structure of ND and hydrogen groups on its surface. It was established that oxygen-containing Lewis sites and unsaturated surface C=C bonds on CNTs play a key role in the conversion of alcohols while just the basic oxygen-containing centers on the ND surface responsible for the catalysis on it. UNFs-N, containing 10% nitrogen, exhibit catalytic activity only in conversion of primary alcohols, that allows to judge about the participation only of nucleophilic nitrogen-containing groups in conversion of alcohols.
