Adsorption of Gases on Solids01:28

Adsorption of Gases on Solids

219
Adsorption is a process where molecules, known as the adsorbates, accumulate on a surface, which is referred to as the adsorbent or substrate. Occurring at the solid-gas interface, this phenomenon is crucial in various scientific and industrial contexts. The reverse of adsorption is desorption.Two types of adsorptions exist: physical (physisorption) and chemical (chemisorption). Physisorption involves gas molecules held to the solid's surface by relatively weak intermolecular van der Waals...

Adsorption Isotherms I01:29

Adsorption Isotherms I

168
Adsorption isotherms are mathematical models that describe how molecules in a gas or liquid phase interact with surfaces. Two of the most common isotherm models are the Langmuir and Freundlich isotherms, which relate to Type I monolayer chemisorption. The Langmuir model is based on four key assumptions:• Adsorption cannot exceed monolayer coverage.• All surface sites are equivalent.• Molecules adsorb only at vacant sites.• There are no interactions between adsorbed...

Heterogeneous Catalysis

111
Heterogeneous catalysis involves a catalyst in a different phase from the reactants. It is a process where the catalyst and the reactants are in distinct phases, typically solid and gas or liquid.Most heterogeneous catalysts are metals, metal oxides, or acids. The list includes transition metals like iron (Fe), cobalt (Co), nickel (Ni), palladium (Pd), platinum (Pt), chromium (Cr), manganese (Mn), tungsten (W), silver (Ag), and copper (Cu). These metals possess partially vacant d orbitals that...

Adsorption Isotherms II01:25

Adsorption Isotherms II

109
Brunauer, Emmett, and Teller (BET) introduced a theory in 1938 that modified Langmuir's assumptions to explain multilayer physical adsorption. This theory is applicable to Type II isotherms and provides a more realistic picture of adsorption processes. The BET theory assumes a uniform solid surface with localized adsorption sites, where adsorption at one site doesn't affect adsorption at neighboring sites. This theory also allows for the possibility of additional molecules being adsorbed on top...

Noncovalent Attractions in Biomolecules02:35

Noncovalent Attractions in Biomolecules

66.1K
Noncovalent attractions are associations within and between molecules that influence the shape and structural stability of complexes. These interactions differ from covalent bonding in that they do not involve sharing of electrons.
Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.
Hydrogen bonding results from the electrostatic attraction of a hydrogen atom covalently bonded to a strong-electronegative atom like oxygen,...

Area of Science:

  • Surface Science
  • Catalysis
  • Materials Chemistry

Background:

  • Understanding CO2 adsorption on metal surfaces is key for catalytic conversion.
  • Elucidating molecular interactions informs reaction mechanisms.

Purpose of the Study:

  • To determine the molecular structure of CO2 adsorbed on Ru(0001).
  • To investigate the self-assembly and interactions of CO2 molecules on metal surfaces.

Main Methods:

  • Scanning Tunneling Microscopy (STM) for structural analysis.
  • Density Functional Theory (DFT) calculations for energetic and structural validation.

Main Results:

  • CO2 adopts a V-shape geometry on Ru(0001), deviating from its linear gas-phase structure.
  • At 77 K, CO2 forms disordered structures and small (2 × 2) domains.
  • Upon annealing to 250 K, remaining CO2 molecules form trimers with distinct configurations and interaction energies.
  • A cyclic trimer configuration is more stable (40 meV) than a parallel trimer.

Conclusions:

  • CO2 adsorption on Ru(0001) leads to significant structural changes and self-assembly into ordered trimers.
  • The relative orientation of CO2 molecules dictates trimer stability and interaction energies.
  • These findings provide insights into CO2 surface chemistry relevant to catalysis.
