In this study, by employing density functional theory (DFT) calculations, the atomic arrangements and energetics of an extensive set of Au–Rh structures in a confined (2 × 1) surface cell on a Rh(111) substrate are investigated. An ordered surface alloy layer composed of 50% Au and 50% Rh is identified as the energetically favored structure, which corresponds to a configuration proposed previously based on scanning tunneling microscopy (STM) imaging [Óvári et al. PCCP 2016, 18, 25230]. Comparing this surface alloy with another candidate structure in terms of Rh and Au adsorption characteristics, the bonding preference among Rh and Au species is recovered. DFT-based simulated STM images reveal bias-voltage-dependent contrast differences among selected corrugated surface layer structures at various Au coverages. Furthermore, several new experimental results obtained by STM and low energy ion scattering (LEIS) on the thermally induced formation of the ordered Au–Rh surface alloy are also presented in this work.

Scanning tunneling microscopy and X-ray photoelectron spectroscopy measurements were carried out to characterize the gold nanoparticles on clean and hexagonal boron nitride (h-BN) covered Rh(111). The adsorption of acetaldehyde was not completely hindered by gold atoms; however, depending on the structure of the outermost bimetallic layer (surface alloy) the dissociation of the parent molecule was suppressed, namely the production of carbon monoxide was inhibited by the gold domains. Our measurements with acetaldehyde on Au/h-BN/Rh(111) confirmed the observation that the lack of suitable adsorption sites eliminates the formation of CO. Nevertheless, increased coverage of gold enhanced the amount of adsorbed aldehyde at low temperature. We may predict that the low reactivity of acetaldehyde on Au/h-BN/Rh(111) significantly determine the ethanol decomposition mechanism on this surface.}, year = {2018}, eissn = {1572-9028}, pages = {1247-1256}, orcid-numbers = {Farkas, Arnold Péter/0000-0002-9392-7221; Szitás, Ádám/0000-0002-3550-0481; Gubó, Richard/0000-0001-6612-7264; Óvári, László/0000-0001-8991-2708; Berkó, András/0000-0002-6934-3808; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:3368595, title = {Tailoring the hexagonal boron nitride nanomesh on Rh(111) with gold}, url = {https://m2.mtmt.hu/api/publication/3368595}, author = {Gubó, Richard and Vári, Gábor and Kiss, János and Farkas, Arnold Péter and Palotás, Krisztián and Óvári, László and Berkó, András and Kónya, Zoltán}, doi = {10.1039/C8CP00790J}, journal-iso = {PHYS CHEM CHEM PHYS}, journal = {PHYSICAL CHEMISTRY CHEMICAL PHYSICS}, volume = {20}, unique-id = {3368595}, issn = {1463-9076}, abstract = {It is known that the hexagonal boron nitride (h-BN) monolayer has a periodically corrugated structure on Rh(111), termed "nanomesh", while the h-BN layer is planar on close packed surfaces of coinage metals (Cu, Ag, Au) due the weak interaction. Our studies aimed at understanding the metal-h-BN interaction, when both Rh and Au are present. On the one hand, the growth and thermal properties of gold deposited on h-BN nanomesh prepared on Rh(111) was studied. On the other hand, the formation of h-BN was examined on Au/Rh surface alloys prepared by the deposition of Au on Rh(111) and subsequent annealing at 1000 K. In each case, the h-BN was prepared by the decomposition of borazine at about 1000 K. Low energy ion scattering (LEIS), X-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) measurements revealed that the growth of Au on h-BN/Rh(111) at room temperature leads to the formation of mainly three dimensional (3D) gold nanoparticles, although at low coverages (< 0.2 ML) 2D particles formed as well. Stepwise annealing to higher temperatures induces the intercalation of Au below the nanomesh, which was complete at around 1050 K. Some agglomeration and desorption of Au also took place. Interestingly, the nanomesh structure was observable after intercalation up to relatively large Au coverages. Measurements performed in the reverse order, namely exposing a Au/Rh(111) surface alloy to borazine, revealed that Rh atoms get covered by h-BN (or by its precursors) at significantly smaller borazine exposures than Au atoms. The nanomesh structure was essentially present up to a gold coverage of 0.9 ML, but with a smaller pore diameter, while it gradually disappeared at higher gold amounts. This way the application of surface alloy supports provides a key for gradual tuning of the mesh morphology. Density functional theory calculations confirmed the decreased pore diameter of the BN layer upon the formation of a surface Rh-Au alloy layer.}, year = {2018}, eissn = {1463-9084}, pages = {15473-15485}, orcid-numbers = {Gubó, Richard/0000-0001-6612-7264; Farkas, Arnold Péter/0000-0002-9392-7221; Palotás, Krisztián/0000-0002-1914-2901; Óvári, László/0000-0001-8991-2708; Berkó, András/0000-0002-6934-3808; Kónya, Zoltán/0000-0002-9406-8596} } @article{MTMT:3317282, title = {Variation of SMSI with the Au:Pd Ratio of Bimetallic Nanoparticles on TiO2(110)}, url = {https://m2.mtmt.hu/api/publication/3317282}, author = {Gubó, Richard and Chi, M Yim and Michael, Allan and Chi, L Pang and Berkó, András and Geoff, Thornton}, doi = {10.1007/s11244-017-0854-5}, journal-iso = {TOP CATAL}, journal = {TOPICS IN CATALYSIS}, volume = {61}, unique-id = {3317282}, issn = {1022-5528}, year = {2018}, eissn = {1572-9028}, pages = {308-317}, orcid-numbers = {Gubó, Richard/0000-0001-6612-7264; Berkó, András/0000-0002-6934-3808} } @article{MTMT:3110742, title = {Interaction of Gold with a Pinwheel TiO similar to 1.2 Film Formed on Rh(111) Facet: STM and DFT Studies}, url = {https://m2.mtmt.hu/api/publication/3110742}, author = {Mutombo, P and Gubó, Richard and Berkó, András}, doi = {10.1021/acs.jpcc.6b03959}, journal-iso = {J PHYS CHEM C}, journal = {JOURNAL OF PHYSICAL CHEMISTRY C}, volume = {120}, unique-id = {3110742}, issn = {1932-7447}, year = {2016}, eissn = {1932-7455}, pages = {12917-12923}, orcid-numbers = {Gubó, Richard/0000-0001-6612-7264; Berkó, András/0000-0002-6934-3808} }
