Abstract
The mechanism of selective proton electroadsorption in the pores of carbon molecular sieves was studied. The carbons used in this work were made from pyrolysis of a polymer precursor under the flow of nitrogen. Carbon dioxide was employed at ambient pressure for activation at 900°C, and concentrated nitric acid was used at room temperature. It was shown that protic environment exists as water molecules adsorbed on the surface interacts strongly with surface groups of the carbon molecular sieving pores.
