Surface oxygen complexes on Spheron 6, which thermally desorb as CQ, appear to be responsible for the acidity of the carbon. The base uptake of samples degassed at various temperatures has been related to the amounts of oxygen complex remaining on the surface. Two types of acidic oxides, both of whi

The extent of chemically detectable acidic surface oxides on graphite has been compared to the total coverage of the surface with oxide. Evolved .gas analysis techniques using a mass spectrometer have been used to determine the composition of the gases evolved (CO, CO,, Hz and H,O) on thermal decomp
Hydrogen adsorption studies at 78 K and pressures up to 40 atmosphere were conducted on nine commercial activated carbon samples. The amount of hydrogen adsorbed increased with increasing surface area. Surface modification consisting of controlled high-temperature reduction and oxidation revealed th
