Site-dependent reactivity of MoS2 nanoparticles in hydrodesulfurization of thiophene
Autor: Norberto Salazar, Srinivas Rangarajan, Jonathan Rodríguez-Fernández, Manos Mavrikakis, Jeppe V. Lauritsen
Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-9 (2020)
MoS2 nanoparticles catalyze the extraction of heteroatom S in hydrocarbons by adsorption onto S vacancies. Here, the authors show that S vacancy properties are highly site sensitive and that adsorption of thiophene leads to self-generation of a more

Autor: Signe S. Grønborg, Norberto Salazar, Albert Bruix, Jonathan Rodríguez-Fernández, Sean D. Thomsen, Bjørk Hammer, Jeppe V. Lauritsen
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-11 (2018)
Rational design of a hydrodesulfurization catalyst relies on a fundamental understanding of its working principles. Here, the authors use scanning tunneling microscopy to directly visualize and quantify hydrogen-induced reshaping and edge activation

Publikováno v: Sun, Z, Curto, A, Rodríguez-Fernández, J, Wang, Z, Parikh, A, Fester, J, Dong, M, Vojvodic, A & Lauritsen, J V 2021, ' The Effect of Fe Dopant Location in Co(Fe)OOH x Nanoparticles for the Oxygen Evolution Reaction ', ACS Nano, vol. 15, no. 11, pp. 18226-18236 . https://doi.org/10.1021/acsnano.1c07219
The addition of iron (Fe) can in certain cases have a strong positive effect on the activity of cobalt and nickel oxide nanoparticles in the electrocatalytic oxygen evolution reaction (OER). The reported optimal Fe dopant concentrations are, however,

Water dissociation on mixed Co-Fe oxide bilayer nanoislands on Au(111)
Autor: Zhaozong Sun, Jeppe Lauritsen, Jonathan Rodríguez-Fernández
Publikováno v: Sun, Z, Rodríguez-Fernández, J & Lauritsen, J V 2022, ' Water dissociation on mixed Co-Fe oxide bilayer nanoislands on Au(111) ', Journal of Physics Condensed Matter, vol. 34, no. 16, 164004 . https://doi.org/10.1088/1361-648X/ac513a
We investigate the hydroxylation behaviour of mixed Co–Fe oxide nanoislands synthesized on a Au(111) surface under exposure to water vapour at vacuum conditions. The pure Co and Fe bilayer oxides both become hydroxylated by water exposure in vacuum
