The uncatalyzed and catalyzed heterogeneous oxidn. processes of a batch of fullerenes (e.g., Fullerite) were investigated at 25-900 under various non-isothermal heatings.

With respect to these carbons, the fullerene sample showed a higher reactivity in both uncatalyzed and catalyzed processes. The contact between catalyst (K-promoted V-Cu) and carbon material strongly affected the catalytic oxidn.

Abstract
The uncatalyzed and catalyzed heterogeneous oxidn. processes of a batch of fullerenes (e.g., Fullerite) were investigated at 25-900 under various non-isothermal heatings. The results are compared to those obtained with more conventional and well-characterized carbons. With respect to these carbons, the fullerene sample showed a higher reactivity in both uncatalyzed and catalyzed processes. The contact between catalyst (K-promoted V-Cu) and carbon material strongly affected the catalytic oxidn. A high selectivity of the catalyst toward CO2 formation was obsd. and the ability of the catalyst to catalyze the gas-phase reaction of CO to CO2 at >400 was shown.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
