V coverages of <jats:italic>\u03b8<\/jats:italic><jats:sub>V<\/jats:sub>=0.2 and 0.4 MLE (monolayer equivalents) were studied. Pulses display a c(2\u00d72) pattern in the reduced part and (1\u00d72) and c(2\u00d78) structures in the oxidized part of the surface. At <jats:italic>\u03b8<\/jats:italic><jats:sub>V<\/jats:sub>=0.4 MLE (1\u00d72)\/(1\u00d74) patterns with streaks along the [001]\u2010direction at the 1\/8 positions are present on the oxidized part of the surface. This phase can be assigned to V\u2010oxide. On a tentative basis, an excitation mechanism for pulses is presented, Annealing the surface to 990\u2005K under reaction conditions results in a macroscopic hole pattern in which holes of low VO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> coverage are surrounded by a V\u2010oxide layer. Chemical waves propagate inside the holes as well as on the VO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> covered parts of the surface. The results demonstrate for the first time that also in supported oxidic overlayers selforganization processes can take place leading to chemical waves and a large scale redistribution of the oxide.<\/jats:p>","DOI":"10.1002\/cphc.202400186","type":"journal-article","created":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T06:29:01Z","timestamp":1716359341000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<i>In situ<\/i> Low\u2010Energy Electron Microscopy of Chemical Waves on a Composite V\u2010oxide\/Rh(110) Surface"],"prefix":"10.1002","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3722-5767","authenticated-orcid":false,"given":"Bernhard","family":"von Boehn","sequence":"first","affiliation":[{"name":"Institute of Physical Chemistry and Electrochemistry Leibniz University Hannover  Callinstr. 3\u2005A 30167 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8397-5644","authenticated-orcid":false,"given":"Jon\u2010Olaf","family":"Krisponeit","sequence":"additional","affiliation":[{"name":"Institute of Solid State Physics University of Bremen  Otto-Hahn-Allee 1 28359 Bremen Germany"},{"name":"MAPEX Center for Materials and Processes University of Bremen, Postfach 330 440  28334 Bremen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4154-822X","authenticated-orcid":false,"given":"Jens","family":"Falta","sequence":"additional","affiliation":[{"name":"Institute of Solid State Physics University of Bremen  Otto-Hahn-Allee 1 28359 Bremen Germany"},{"name":"MAPEX Center for Materials and Processes University of Bremen, Postfach 330 440  28334 Bremen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5155-7250","authenticated-orcid":false,"given":"Ronald","family":"Imbihl","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry and Electrochemistry Leibniz University Hannover  Callinstr. 3\u2005A 30167 Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,7,10]]},"reference":[{"key":"e_1_2_9_1_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr300307n"},{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.progsurf.2003.09.001"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevB.69.155403"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpcc.7b04809"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11244-020-01373-1"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.115.136102"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7CP01890H"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpcc.8b00852"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcat.2020.03.016"},{"key":"e_1_2_9_10_1","volume":"8","author":"Boehn B.","year":"2020","journal-title":"Front.
