WebAs graphitic-N is largely responsible for the irreversible capacity, the anode's performance was significantly increased. Compared to general N-doped carbons with high graphitic-N proportion (>50%) and low N content (<15 at%), LGNCs delivered a low proportion of 10.8%–17.2% within the high N-doping content of 14.5–42.7 at%, ...

Moreover, electron paramagnetic resonance, radical scavenging tests, and in situ Raman spectra demonstrated that the generated common reactive oxygen species did not contribute to ...
WebThe substitution of F by OH and hydroxylation of the piperazine ring might be induced by SO 4 •– and • OH, whose formation was affected by C–O, Co(0), Co–N x, graphitic N, and defects. The findings provided new insights into reaction mechanisms in PMS-AOP systems and rational design of catalysts for ROS-oriented degradation of pollutants. WebTo elucidate the formation of hexagonal graphitic-N, we explored oxygen reduction and subsequent nitrogen-doping processes on defective graphene oxides with single vacancies for the first time. All possible reaction pathways were taken into account, and the results demonstrate that the formation of graphitic-N from NH 3 and defective graphene ...
