Based on in situ Fourier transform infrared (FT-IR) spectra and in situ electrochemical impedance spectroscopy (EIS), it is found that the oxygen-containing functional groups regulate the components of solid electrolyte interphase (SEI), leading to the formation of highly conductive, intact and ...
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
The effects of oxygen-containing functional groups on the surface roughness of graphene oxide are thoroughly studied using three-dimensional atomic force microscopy images, ball-and-stick model and wire-frame view results. Moreover, X-ray diffraction method and Fourier transform infrared spectroscopy are...
Our group has previously studied the annealing process and confirmed the removal of oxygen-containing functional groups (OFGs) would bring benefits to ORR activity. However, the removal of which kind(s) of functional group will influence the ORR activity most has not been verified. In this work...
A previous study demonstrated that CMM can function as a substrate because residual oxygen-containing functional groups are generated in the catalytic reaction and the CMMs strongly promote oxygen storage on the catalyst surface26. To further evaluate the electrocatalytic activities of the complex Pt-...
to the electrochemical tests, N-doped carbon prepared at 400 °C showed excellent two-electron ORR with a selectivity of 93% over a wide potential range from 0.17 to 0.6 V (vs. RHE) due to the combination of pyridinic-N, pyrrolic-N, and the surface oxygen-containing functional groups. ...

(Table2), 38 with no known function and others identified as transcription factors and pentatricopeptide repeat-containing proteins (PPR), possibly participating in ROS signal transduction from the chloroplast to the nucleus and vice versa [55]. This indicates that nuclear gene expression might be ...
Highly reactive oxygen-containing species of high oxidative potential are termed ROS. These species mainly include H2O2, superoxide anion radicals, and hydroxyl radicals, which play especially important roles in homeostasis and pathologies in humans. For instance, H2O2, a molecular ROS, have been demon...
