The influence of the Sr\/Ba substitution on the structure, crystallization, morphology, and photocatalytic efficiency was investigated and the samples were fully characterized. On the basis of X\u2010ray diffraction results, as the Ba content in the SrSnO<jats:sub>3<\/jats:sub> lattice increases, a symmetry increase was observed from the orthorhombic perovskite structure for SrSnO<jats:sub>3<\/jats:sub> to the cubic BaSnO<jats:sub>3<\/jats:sub> structure. The analysis of the sample morphology by SEM reveals that the Sr<jats:sub>1\u2212<jats:italic>x<\/jats:italic><\/jats:sub>Ba<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub>SnO<jats:sub>3<\/jats:sub> samples favor the formation of nanorods (500\u2005nm\u20135\u2005\u03bcm in diameter and several micrometers long). The photophysical properties were examined by UV\/Vis diffuse reflectance spectroscopy. The band gap decreases from 3.85 to 3.19\u2005eV with increasing Ba<jats:sup>2+<\/jats:sup> content. Furthermore, the photocatalytic properties were evaluated for the hydroxylation of terephthalic acid (TA). The order of the activities for TA hydroxylation was Sr<jats:sub>0.8<\/jats:sub>Ba<jats:sub>0.2<\/jats:sub>SnO<jats:sub>3<\/jats:sub>&gt;SrSnO<jats:sub>3<\/jats:sub>&gt;BaSnO<jats:sub>3<\/jats:sub>&gt;Sr<jats:sub>0.6<\/jats:sub>Ba<jats:sub>0.4<\/jats:sub>SnO<jats:sub>3<\/jats:sub>&gt;Sr<jats:sub>0.2<\/jats:sub>Ba<jats:sub>0.8<\/jats:sub>SnO<jats:sub>3<\/jats:sub>. The highest photocatalytic activity was observed for Sr<jats:sub>0.8<\/jats:sub>Ba<jats:sub>0.2<\/jats:sub>SnO<jats:sub>3<\/jats:sub>, and this can be attributed to the synergistic impacts of the modification of the crystal structure and morphology, the relatively large surface area associated with the small crystallite size, and the suitable band gap and band\u2010edge position.<\/jats:p>","DOI":"10.1002\/cssc.201700615","type":"journal-article","created":{"date-parts":[[2017,6,6]],"date-time":"2017-06-06T23:22:59Z","timestamp":1496791379000},"page":"3387-3401","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":52,"title":["Ionic\u2010Liquid\u2010Assisted Microwave Synthesis of Solid Solutions of Sr<sub>1\u2212<i>x<\/i><\/sub>Ba<sub><i>x<\/i><\/sub>SnO<sub>3<\/sub> Perovskite for Photocatalytic Applications"],"prefix":"10.1002","volume":"10","author":[{"given":"Tarek","family":"Alammar","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering Iowa State University  Ames IA 50011 USA"},{"name":"The Ames Laboratory U.S. Department of Energy  Ames IA 50011 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Igor I.","family":"Slowing","sequence":"additional","affiliation":[{"name":"The Ames Laboratory U.S. Department of Energy  Ames IA 50011 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jim","family":"Anderegg","sequence":"additional","affiliation":[{"name":"The Ames Laboratory U.S. Department of Energy  Ames IA 50011 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2800-1684","authenticated-orcid":false,"given":"Anja\u2010Verena","family":"Mudring","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Iowa State University  Ames IA 50011 USA"},{"name":"The Ames Laboratory U.S. Department of Energy  Ames IA 50011 USA"},{"name":"Department of Materials and Environmental Chemistry Stockholm University  Svante Arrhenius v\u00e4g 16C 106 91 Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,17]]},"reference":[{"key":"e_1_2_6_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cplett.2005.10.122"},{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-2738(99)00306-9"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1088\/0953-8984\/27\/36\/365401"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jallcom.2015.08.227"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.2778631"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10971-012-2896-2"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.materresbull.2012.05.044"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10854-015-3769-6"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jallcom.2006.05.110"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/cm071321d"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6RA02980A"},{"key":"e_1_2_6_12_1","doi-asserted-by":"crossref","first-page":"691503","DOI":"10.1155\/2012\/691503","author":"Motshekga S.","year":"2012","journal-title":"J.
