Surface oxides on carbon and their analysis: a critical assessment
TL;DR: The methods for the determination of various types of oxygen surface functions on carbon materials are briefly described, and their relative advantages and problems that may arise are discussed in this paper, where acidimetric titration techniques, IR spectroscopy, XPS, thermal desorption spectroscopic, and electrokinetic measurements are described.

On the characterization of acidic and basic surface sites on carbons by various techniques
TL;DR: In this paper, the surface groups of active carbons can also be characterized by immersion calorimetry and the variation of the pH of the point of zero charge with the total oxygen content of the surface.

Surface Oxides of Carbon
TL;DR: In this paper, it was found that the reaction of oxygen with microcrystalline carbon at 400-450°C yields four groups of different acidities: strongly acidic, weakly acidic, carboxyl and carbonyl groups.

A new interpretation of the Acidic and Basic structures in Carbons. II. The Chromene-carbonium ion couple in Carbon
VA Garten,DE Weiss,JB Willis +2 more
TL;DR: In this paper, a theoretical interpretation of the electrochemical behavior of the chromene-carbonium ion couple is presented, which is in good quantitative agreement with the observed behaviour of a cathodically polarized carbon electrode in acid solution.
