Unraveling the mechanism of ligands regulating electronic structure of MN4 sites with optimized ORR catalytic performance

Bing Li et al.

Summary: As an alternative to Pt/C catalysts for the oxygen reduction reaction (ORR), metal-nitrogen-carbon (M-N-C) catalysts have emerged as promising materials. However, the ORR catalytic mechanism of M-N-C catalysts is still unclear. In this work, oxygen-containing ligands are introduced to better explain the activity sequence of Fe/Co/MnN4 and Pt/C. It is found that a self-modification mechanism in M-N-C materials can adjust the adsorption for intermediates, facilitating the ORR process. Furthermore, the relationship between electronic structure and catalytic activity is explored using the integrated crystal orbital Hamilton population (iCOHP) as the ORR activity descriptor.

Substituent effects of nitro group in cyclic compounds

Anna Jezuita et al.

Summary: Numerous studies have explored the electron-withdrawing ability of the nitro group, with the substituent effects being well described using traditional constants or quantum chemistry models. Analysis of substituent effects in various systems suggests strong pi-electron interactions with electron-donating substituents due to resonance effects. The use of models like pEDA/sEDA allows for measuring electron transfer from the ring to the nitro group.
