VSEPR Theory

15.4K
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure around a central atom from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them. The electrons in the valence shell of a central atom form either bonding...

The molecular orbital theory describes the distribution of electrons in molecules in a manner similar to the distribution of electrons in atomic orbitals. The region of space in which a valence electron in a molecule is likely to be found is called a molecular orbital. Mathematically, the linear combination of atomic orbitals (LCAO) generates molecular orbitals. Combinations of in-phase atomic orbital wave functions result in regions with a high probability of electron density, while...

Radical Reactivity: Steric Effects

2.6K
The presence of electron-donating, electron-withdrawing, or conjugating groups adjacent to a radical center, imparts electronic stabilization to the radicals. Examples of such electronically-stabilized radicals are triphenylmethyl, tetramethylpiperidine‐N‐oxide, and 2,2‐diphenyl‐1‐picrylhydrazyl. These radicals are remarkably stable and are known as persistent radicals. Some of the persistent radicals can even be isolated and purified.

Area of Science:

  • Heterogeneous Catalysis
  • Materials Science
  • Surface Chemistry

Background:

  • Atomically dispersed gold (Au) catalysts offer well-defined active sites but suffer from poor structural stability.
  • Existing Au catalysts exhibit limited interactions with structurally complex multi-functionalized molecules (SCMMs), hindering selective catalysis.
  • Stabilizing single-atom catalysts (SACs) and enhancing their recognition of complex substrates are critical challenges.

Purpose of the Study:

  • To develop a generalizable strategy for stabilizing single Au atoms on ceria (CeO2) supports.
  • To enhance the interaction between Au catalysts and SCMMs through multi-site recognition.
  • To improve the electrochemical catalytic performance for SCMMs.

Main Methods:

  • Synthesis of defect-rich CeO2 supported single Au atoms modified with Pt (Au1Pt1-CeO2).
  • Experimental characterization (e.g., spectroscopy, microscopy) and computational analyses (e.g., DFT).
  • Electrochemical catalytic performance evaluation using norfloxacin (NOR) as a model SCMM.

Main Results:

  • Pt incorporation stabilizes Au single atoms by suppressing metallic Au° formation via strengthened Au-O orbital coupling and electronic redistribution.
  • The Au1Pt1-CeO2 catalyst exhibits a multi-centered configuration enabling cooperative interactions with NOR's functional groups (F, -COOH, -C=O).
  • This leads to enhanced electrochemical catalytic activity and spatially precise recognition of SCMMs.

Conclusions:

  • The adjacency-assisted strategy effectively stabilizes single Au atoms and promotes multi-site recognition for SCMMs.
  • Pt's electronic modulation is key to stabilization, a principle extendable to other platinum group metals (PGMs).
  • This work offers a new perspective for designing robust, recognition-oriented catalysts for complex molecules.
