We present here a study examining the adsorption and reaction of methanol on magnetite Fe3O4(001) at cryogenic temperatures using a combination of temperature programmed desorption, x-ray photoelectron spectroscopy, and scanning tunneling microscopy. The methanol desorption profile from Fe3O4(001) is complex, exhibiting peaks at 140 K, 173 K, 230 K, and 268 K, corresponding to the desorption of intact methanol, as well as peaks at 341 K and 495 K due to the reaction of methoxy intermediates. The saturation of a monolayer of methanol corresponds to \u223c5 molecules\/unit cell (u.c.), which is slightly higher than the number of surface octahedral iron atoms of 4\/u.c. We probe the kinetics and thermodynamics of the desorption of molecular methanol using inversion analysis. The deconvolution of the complex desorption profile into individual peaks allows for calculations of both the desorption energy and the prefactor of each feature. The initial 0.7 methanol\/u.c. reacts to form methoxy and hydroxy intermediates at 180 K, which remain on the surface above room temperature after intact methanol has desorbed. The methoxy species react via one of two channels, a recombination reaction with surface hydroxyls to form additional methanol at \u223c350 K and a disproportionation reaction to form methanol and formaldehyde at \u223c500 K. Only 20% of the methoxy species undergo the disproportionation reaction, with most of them reacting via the 350 K pathway.<\/jats:p>","DOI":"10.1063\/1.5139418","type":"journal-article","created":{"date-parts":[[2020,2,10]],"date-time":"2020-02-10T09:37:35Z","timestamp":1581327455000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":19,"title":["Adsorption and reaction of methanol on Fe3O4(001)"],"prefix":"10.1063","volume":"152","author":[{"given":"Matthew D.","family":"Marcinkowski","sequence":"first","affiliation":[{"name":"Physical and Computational Sciences Directorate and Institute for Integrated Catalysis, Pacific Northwest National Laboratory 1 , Richland, Washington 99354,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kr\u00e6n C.","family":"Adamsen","sequence":"additional","affiliation":[{"name":"Interdisciplinary Nanoscience Center (iNano) and Department of Physics and Astronomy, Aarhus University 2 , DK-8000 Aarhus C,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nassar","family":"Doudin","sequence":"additional","affiliation":[{"name":"Physical and Computational Sciences Directorate and Institute for Integrated Catalysis, Pacific Northwest National Laboratory 1 , Richland, Washington 99354,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2599-8212","authenticated-orcid":false,"given":"Marcus A.","family":"Sharp","sequence":"additional","affiliation":[{"name":"Physical and Computational Sciences Directorate and Institute for Integrated Catalysis, Pacific Northwest National Laboratory 1 , Richland, Washington 99354,","place":["USA"]},{"name":"Voiland School of Chemical Engineering and Bioengineering, Washington State University 3 , Pullman, Washington 99163,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7145-1963","authenticated-orcid":false,"given":"R.
