Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is still difficult. Here we investigate the r
Determinations of reactive oxygen-containing functional groups were performed by usual chemical derivatization methods of four humic acids isolated from soils and deltaic sediments. Statistical tests and calculations based on elemental analysis demonstrated the validity and limits of these techniques and allow...

Density functional theory was used to study the effects of different types of oxygen-containing functional groups on the adsorption of oxygen molecules and single active oxygen atoms on carbonaceous materials. During gasification or combustion reactions of carbonaceous materials, oxygen-containing functional...
Drying of brown coals in nitrogen resulted in a significant increase in their aromaticity and a lower concentration of oxygen-containing functional groups. The loss of oxygen was confirmed by measuring the O/C ratio of raw and dried ... A Tahmasebi,J Yu,S Bhattacharya - 《Energy & Fuels》...
A similar effect is seen on carbon supports where the rate of platinum nanoparticle agglomeration is seen to reduce when carbon supports are modified with nitrogen and oxygen containing functional groups that strongly interact with nanoparticles66,67. Likewise, it suggests that Pt nanoparticles can ...

28, 29, 30 The oxygen-containing surface functional groups are also demonstrated by attenuated total reflection (ATR) Fourier transform infrared spectroscopy (FTIR). The band at ∼1,750 cm−1 can be assigned to C=O, while the band from 1,000 to 1,300 cm−1 can be assigned to C...
The FT-IR spectra of the C/Fe3O4 HGs show thee peaks, located at 2357, 1738 and 1365 cm − a, which can be ascribed to the oscillation of carboxyl groups (–COOH). The presence of carboxyl groups as oxygen-containing functional groups in the C/Fe3O4 HGs is clearly evident by a...
