Despite its importance, characterizing the surface composition of bi\u2010MNPs is still extremely difficult with existing techniques. Here, we show that the challenge is approached by combining extended X\u2010ray absorption fine structure (EXAFS) analyses and modeling calculations. A generally applicable methodology using an ethylene glycol\u2010assisted redox transmetallation (EG\u2010RTM) strategy has been used to deduce the surface Pt composition of various Pt\u2013Ru bi\u2010MNPs to facilitate discussion of their electrochemical catalytic efficiency. Further discussion is focused on SERS, related to the surface Ag content of various Ag\u2013Pt bi\u2010MNPs formed in ethylene glycol solutions at controlled pH values. Although the present methodology is demonstrated on fcc structured bi\u2010MNPs it should be transferable to bi\u2010MNP structures with different shapes and also to ternary nanoparticles. The proposed methodology enables us to deduce the surface composition of bi\u2010MNPs from experimental data directly and to estimate the surface composition under real conditions, when compared to simulation. The ability of the present combined modeling and experimental approach makes it a unique tool in our quest to understand the physical and chemical properties of NPs.<\/jats:p>","DOI":"10.1002\/cnma.201500190","type":"journal-article","created":{"date-parts":[[2015,11,27]],"date-time":"2015-11-27T06:02:42Z","timestamp":1448604162000},"page":"117-124","source":"Crossref","is-referenced-by-count":7,"title":["Unravelling Surface Composition of Bimetallic Nanoparticles"],"prefix":"10.1002","volume":"2","author":[{"given":"Ching\u2010Hsiang","family":"Chen","sequence":"first","affiliation":[{"name":"Graduate Institute of Applied Science and Technology National Taiwan University of Science and Technology  43 Keelung Road, Section 4 Taipei 106 Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7633-2058","authenticated-orcid":false,"given":"Chun\u2010Jern","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Taiwan University of Science and Technology  43 Keelung Road, Section 4 Taipei 106 Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1494-2675","authenticated-orcid":false,"given":"Wei\u2010Nien","family":"Su","sequence":"additional","affiliation":[{"name":"Graduate Institute of Applied Science and Technology National Taiwan University of Science and Technology  43 Keelung Road, Section 4 Taipei 106 Taiwan"}]},{"given":"Loka Subramanyam","family":"Sarma","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Taiwan University of Science and Technology  43 Keelung Road, Section 4 Taipei 106 Taiwan"}]},{"given":"Cun Cun Al","family":"Andra","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Taiwan University of Science and Technology  43 Keelung Road, Section 4 Taipei 106 Taiwan"}]},{"given":"Hwo\u2010Shuenn","family":"Sheu","sequence":"additional","affiliation":[{"name":"National Synchrotron Radiation Research Center  Hsin Ann Road 101 Hsinchu 300 Taiwan"}]},{"given":"Din\u2010Goa","family":"Liu","sequence":"additional","affiliation":[{"name":"National Synchrotron Radiation Research Center  Hsin Ann Road 101 Hsinchu 300 Taiwan"}]},{"given":"Jyh\u2010Fu","family":"Lee","sequence":"additional","affiliation":[{"name":"National Synchrotron Radiation Research Center  Hsin Ann Road 101 Hsinchu 300 Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3873-2149","authenticated-orcid":false,"given":"Bing\u2010Joe","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Taiwan University of Science and Technology  43 Keelung Road, Section 4 Taipei 106 Taiwan"},{"name":"National Synchrotron Radiation Research Center  Hsin Ann Road 101 Hsinchu 300 Taiwan"}]}],"member":"311","published-online":{"date-parts":[[2016,1,11]]},"reference":[{"key":"e_1_2_6_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature11115"},{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr100449n"},{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1134569"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1120560"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/C2SC21191B"},{"key":"e_1_2_6_5_1","first-page":"7649","volume":"59","author":"Maciej R.","year":"2011","journal-title":"J.
