Diazomethane has been used to methylate the "active" hydrogen associated with acidic oxides on carbon and graphite surfaces. Analysis of the methoxyl groups so formed showed that the active hydrogen was present as an OH group and that the total active hydrogen content of both carbon and graphite deg

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

Spheron 6 was oxidized with l/l nitric acid and the treated samples were submitted to elemental analysis and oxygenated surface group determination. The active surface area (ASA) of the samples was measured. Analysis was made of the gases (CO, CO?) evolved when the oxidized samples were heat treated
