โœฆ Synopsis

ESR studies of a carbon sample obtained from the partial oxidation of naphtha by the Shell process has been carried out with particular reference to the role of traces of iron present in it. The dried and evacuated sample displays a strong ESR signal that remains unchanged when NO, N,O, SO,, CO, and Hz are allowed to adsorb over it, but water vapor and oxygen strongly reduce the signal. The signal observed is assumed to arise from superparamagnetic iron and its interaction with the carbon matrix.
