A Thermodynamic Investigation of Adsorbate- Adsorbate Interactions of Carbon Dioxide on Nanostructured Carbons
A thermodynamic study of carbon dioxide adsorption on a zeolite-templated carbon (ZTC), a superactivated carbon (MSC-30) and an activated carbon (CNS-201) was carried out at temperatures from 241 to 478 K and pressures up to 5.5 106 Pa. Excess adsorption isotherms were fitted with generalized Langmuir-type equations, allowing the isosteric heats of adsorption and adsorbed-phase heat capacities ...
متن کاملAdsorbate interactions on surface lead to a flattened Sabatier volcano plot in reduction of oxygen
Ab initio electronic-structure calculations of surface catalysis often give changes P0.1 eV for activation energies of intermediate steps when the surface structure or composition is varied, yet P50-fold change in activity according to naive interpretation of the Arrhenius formula is usually not seen in corresponding experiments. To quantitatively analyze this sensitivity inconsistency between ...
متن کاملControlling the electronic structure of graphene using surface-adsorbate interactions
Hybridization of atomic orbitals in graphene on Ni(111) opens a large energy gap of ≈2.8 eV between non-hybridized states at the K-point. Here we use alkali metal adsorbate to reduce and even eliminate this energy gap, and also identify a mechanism responsible for decoupling graphene from the Ni substrate without intercalation of atomic species underneath graphene. Using angle-resolved photoemi...
متن کاملEffects of Solvent on the Structure and Properties of Titanium Dioxide Nanoparticles and Their Antibacterial Activity
Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...
متن کاملProbing surface short range order and inter-adsorbate interactions through IR vibrational spectroscopy: CO on Cu(100).
It is demonstrated that surface vibrational spectroscopy can be used to probe local ordering of adsorbates and the nature of inter-adsorbate interactions through dynamical dipole coupling among neighboring adsorbates. Our studies show that for CO adsorbed on Cu(100), first and second nearest neighbor interactions are repulsive. This repulsion prevents the formation of long range ordered structu...
