Electrochemical role of oxygen containing functional groups on

We have experimentally and theoretically clarified the effect of oxygen functional groups on the capacitive performance of a photochemically treated activated carbon electrode. A high density of C double bond, length as m-dash O group

Impact of Oxygen-Containing Surface Functional Groups on

30 Jun 997 The temperature at which the freshly activated carbon is exposed to oxygen generally determines the nature of these oxygen complexes 2, 3 . The acidic groups include carboxyl, lactone, and hydroxyl functionalities. Carbon

Roles of Oxygen Functional Groups in Hydrogen Sulfide Adsorption

25 Mar 20 9 The interactions of H2S with various oxygen groups on activated carbon were detailed examined by density functional theory. The results indi e that pyrone, carbonyl, ester, and carboxyl groups are active sites for H2S&nb

Effect of the oxygen functional groups of activated carbon on its

Oxygen functional groups on a commercial activated carbon were modified by NH4 2S2O8 oxidation and subsequent annealing at different temperatures. The effects of the surface modifi ion on the electrochemical performance as

Importance of activated carbon& 39;s oxygen surface functional groups

Results suggest that oxygen surface complexes, possibly lactone and carbonyl groups, are the active sites for Hg0 capture. The carbons that have a lower carbon monoxide CO /CO2 ratio and a low phenol group concentration tend to have a&n

Thermal Stability of Oxygen-Containing Functional Groups on

The thermal stability of oxygen-containing functional groups on activated carbon surfaces in a thermal oxidative environment was studied. The Seven Trust activated carbon AC0 was first treated with nitric acid, and the resulting nitric acid-tre

Importance of activated carbon& 39;s oxygen functional groups on

7 Dec 2020 Request PDF Importance of activated carbon& 39;s oxygen functional groups on elemental mercury adsorption The effect of varying physical and chemical properties of activated carbons on adsorption of elemental mercury&nb

Impact of the oxygen functional group of nitric acid-treated activated

25 Apr 20 9 To prepare activated carbon with a high specific surface area, oxygen functional groups OFGs that can serve as useful electron donors during KOH activati.

Improvement of oxygen-containing functional groups on olive stones

Recently, modifi ion of surface structure of activated carbons in order to improve their adsorption performance toward especial pollutants has gained great interest. Oxygen-containing functional groups have been devoted as the main&nbs
