Summary
Single platinum atoms on C60 (C60Pt-) efficiently activate methane (CH4) at room temperature. The unique C60 support enhances catalytic activity and selectivity for direct methane conversion.
Area of Science:
- Catalysis
- Materials Science
- Surface Chemistry
Background:
- Supported single-atom catalysts (SACs) are promising for selective C-H bond activation.
- Direct conversion of methane (CH4) to value-added chemicals is a significant challenge.
Purpose of the Study:
- To investigate the catalytic activity of single platinum atoms supported on C60 for methane activation.
- To elucidate the role of the C60 support in enhancing catalyst performance.
Main Methods:
- Utilized state-of-the-art mass spectrometry.
- Employed newly designed variable-temperature double ion trap reactors.
- Immobilized single Pt- atoms on C60 supports.
Main Results:
- Observed significantly enhanced reactivity of C60Pt- toward CH4 activation at room temperature compared to bare Pt-.
- Demonstrated that the C60 support modifies the electronic state of Pt- (Pt- → Pt0), enhancing orbital interactions with CH4.
- Showcased the electron-buffering capability of C60 for selective CH4 activation via single C-H bond cleavage.
Conclusions:
- The C60 support plays a crucial role in enhancing the activity and selectivity of single-atom catalysts for methane activation.

49.3K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

01:27Radical Substitution: Halogenation of Alkanes and Alkyl Substituents
8.7K
In the presence of heat or light, alkanes react with molecular halogens to form alkyl halides by a substitution reaction called radical halogenation. This reaction has three steps: initiation, propagation, and termination, as seen in the radical chlorination of methane to produce methyl chloride.
In the initiation step of the reaction, the chlorine molecule undergoes homolytic cleavage in the presence of light or heat, forming two highly reactive chlorine radicals. Propagation occurs in two...

5.1K
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

3.4K
Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
