Oxygen treatment rendered NCD hydrophilic by the appearance of surface oxygen containing groups.
The data obtained for pristine and modified MWCNTs suggest little influence of the surface oxygen-containing groups on a formation of the EDL in NaClO4 electrolyte.
The profiles obtained gave an estimate of the surface oxygen-containing groups.
Surface oxygen-containing species were used as the probing molecule for revealing the surface reactivity.
In order to quantitatively confirm and compare the change of the oxygen-containing groups, we calculated the peak area ratios of oxygen-containing groups to the total carbon bonds.
The reaction is limited by the amount of surface oxygen.
The change of oxygen-containing functional groups in modified coals make their surface structure complex, and the spatial distribution of the network pore structure become more complex which will form a three-dimensional surface.
After carboxylation of GO, the changes in the content of oxygen-containing groups caused the slight increase of total oxygen content (from 38.6 to 39.7 at. %).
For the electrochemically oxidised electrode, the cathodic photocurrent transient at a fixed potential changed reproducibly with changing solution pH, owing to the participation of the oxygen-containing surface groups in acid base equilibrium with the solution.
Fe3O4/PCC MNPs owned negatively charged surface with oxygen-containing groups and showed a strong adsorption capacity and fast adsorption rates for the removal of cationic dyes in water.
