An HREELS investigation of MnO /Rh(100) model catalyst

Dynamic Structural Evolution of Mn–Au Alloy and MnOx Nanostructures on Au(111) under Different Atmospheres

“…Depending on the different preparation conditions, O–Mn–O trilayers, MnO(001), and MnO(111) can be prepared on Pt(111). A similar phenomenon was also observed on Rh(100). , Additionally, at higher oxygen partial pressure a transition from rock-salt MnO to spinel Mn 3 O 4 occurred. ,, …”

“…A similar phenomenon was also observed on Rh(100). 33,34 Additionally, at higher oxygen partial pressure a transition from rock-salt MnO to spinel Mn 3 O 4 occurred. 31,38,46 Although growth of MnO and Mn 3 O 4 nanoislands and thin films has been reported on many metal substrates, atomic structure and catalytic properties of these MnO x overlayers still need further investigation.…”

“…Fundamental studies over MnO x nanoislands and thin films have been performed on many metal single crystal substrates, including Pd, − Ag, − Rh, − Cu, , Au, − and Pt. − It is well-known that the symmetry and lattice constant of the substrate surface are critical for epitaxial growth of oxide thin films. For instance, a square oxide overlayer can be obtained on a substrate surface with tetragonal symmetry, such as epitaxial rock salt MnO(001) on Ag(001) , and spinel Mn 3 O 4 (001) on Ag(001) .…”
