Characterization of Carbon-Oxygen Surface Groups

However, the structure of the basic surface oxygen groups is still a matter of dispute. Morterra et al. are emphatic that the basic properties of carbons cannot

Bansal et al. also studied the decomposition of carbon-oxygen surface groups formed on low temperature oxidation of ultra clean surfaces of activated graphon using a mass spectrometer and observed that both CO2 and CO were primary
