Halogens

23.7K
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid. Astatine is a highly unstable radioactive element, so currently, most of its properties are unknown due to its short half-life. Tennessine is a synthetic element also predicted to be in this group.

Radical Formation: Homolysis00:54

Radical Formation: Homolysis

4.5K
A bond is formed between two atoms by sharing two electrons. When this bond is broken by supplying sufficient energy, either two electrons can be taken up by one atom forming ions by the cleavage called heterolysis, or the two electrons are shared by two atoms, with one each creating radicals by the cleavage called homolysis.

¹³C NMR: ¹H–¹³C Decoupling

1.9K
The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...

ortho–para-Directing Deactivators: Halogens

7.0K
Halogens are ortho–para directors. They are more electronegative than carbon. Therefore, as ring substituents, they can withdraw electrons through the inductive effect and deactivate the aromatic ring towards electrophilic substitution. Halogens also have an electron-donating resonance effect on the ring, which influences the orientation of the incoming electrophile. If an electrophile attacks at the ortho or the para position, the halogen donates electrons and stabilizes the intermediate...

Atomic Fluorescence Spectroscopy01:29

Atomic Fluorescence Spectroscopy

1.0K
Atomic fluorescence spectroscopy (AFS) is an analytical technique that involves the electronic transitions of atoms in a flame, furnace, or plasma being excited by electromagnetic (EM) radiation. When these atoms absorb energy, they become excited and subsequently release energy as they return to their original state. This emitted light, or "fluorescence," is observed at a right angle to the incident beam. Both absorption and emission processes transpire at distinct wavelengths, which...

Area of Science:

  • Materials Science
  • Catalysis
  • Environmental Chemistry

Background:

  • Tetrafluoromethane (CF4) is a highly stable per- and polyfluoroalkyl substance (PFAS) challenging to decompose catalytically due to strong C-F bonds.
  • Efficient catalytic decomposition of CF4 is crucial for mitigating environmental pollution from persistent fluorinated compounds.

Purpose of the Study:

  • To develop an effective strategy for activating and decomposing tetrafluoromethane (CF4) at low temperatures.
  • To investigate the role of local electric fields (LEF) in enhancing catalytic activity for CF4 decomposition.

Main Methods:

  • Fabrication of a Ga-Zn dual-atom catalyst supported on Al2O3 (Ga1Zn1/Al2O3) to engineer a strong local electric field (LEF).
  • Utilized spectroscopic characterizations to analyze the interaction between the catalyst and CF4.
  • Performed catalytic decomposition experiments at ultralow temperatures to assess conversion efficiency and stability.

Main Results:

  • The engineered Ga1Zn1/Al2O3 catalyst generated an intense LEF (∼3 × 10^10 N/C), amplifying Lewis acidity and CF4 adsorption.
  • Achieved complete CF4 conversion at an ultralow temperature of 540 °C.
  • Demonstrated a 4.5-fold increase in apparent turnover frequency and halved apparent activation energy compared to pristine Al2O3.
  • Exhibited excellent durability with 100% conversion maintained for over 600 hours.

Conclusions:

  • Dual-atom induced LEF engineering is a potent strategy for activating ultrastable fluorocarbons like CF4.
  • The developed catalyst offers a promising pathway for the sustainable degradation of persistent perfluorinated pollutants.
  • This approach advances catalytic solutions for environmental remediation of challenging industrial byproducts.
