Common structures of CO₂ on structurally different coin metal surfaces

Abstract

A disordered spacer layer (red) allows to form an ordered CO2 layer (green), which is not influenced by the substrate.

The Influence of a Changing Local Environment during Photoinduced CO2 Dissociation

“…On Cu(111), the CO 2 molecules form multi‐domain hexagonal clusters (Figure 4 a). [17] Despite the difference in both, crystal material and face, the results of laser illumination are largely identical (Figure 4 a to c). As on Ag(100), a change in cluster shape is accompanied by a loss in order (compare molecular resolution in the insets in Figure 4 a,b), which is reflected in the shape value S H = , here defined such that a perfect hexagon gives S H =1 to account for the different cluster symmetry (Figure 4 d).…”

“…CO 2 molecules, imaged as protrusions on the quadratic Ag(100) face, form variably‐shaped multi‐domain clusters (Figure 1 a). [17] To identify the progression during the CO 2 dissociation, such a sample is alternately illuminated and imaged (Figure 1 b–d), for laser parameters and other details see the Supporting Information, Experimental Section. The unique setup [18] allows us to image exactly the same region of the surface before and after illumination.…”

“…Thed ifferences between Ag(100) and Cu(111) in the increase of the yield are thus related to astructural mismatch of the adsorbate with the surface (cf.Ref. [17]) and not to the electronic structure of the metal.…”

Ammonium-, phosphonium- and sulfonium-based 2-cyanopyrrolidine ionic liquids for carbon dioxide fixation

“…Understanding of the CO 2 capture perspectives using materials of different nature is currently underway. [7][8][9][10][11][12][13][14][15][16][17][18] The research efforts must be devoted to solving two major problems. First, it is essential to implement energy-saving strategies for efficient energy consumption.…”
