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
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-...

(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 ...
Figure3d and e show three-reactor CLR schemes for H2production, where the overall reactions are the same as the autothermal reforming process. Both schemes share similar reactor configurations and produce three hot gas streams containing concentrated CO2, high purity H2and high-temperature flue gas ...
with different exposed facets is to utilize the amphiphilic function of surfactants. Functional groups (carboxyl, pyridyl, quaternary ammonium, etc.) and halide counter ions of surfactants could be attached to different Pd planes, resulting in ultrathin Pd NSs with exposed {100}, {110}, and {...
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. ...
