A V<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub> catalyst was dispersed in a PTFE (poly-tetra-fluoro-ethylene) used as the catalytic bag-filter material to remove particulate matter and nitrogen oxides contained in the combustion exhaust gas. Macroporous alumina was added into a V<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub>-dispersed\n PTFE to improve the catalytic activity of V<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub> dispersed in the PTFE material. In this study, the textural properties and denitrification performances of the V<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub>-dispersed PTFE materials were examined according to\n the addition of macro-porous alumina. When the denitrification catalyst was solely dispersed in the PTFE material, the catalyst inside the PTFE backbone had low gas-solid contact efficiency owing to the low porosity of the PTFE materials, resulting in low denitrification efficiency. On the\n other hand, the catalytic activity of V<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub> dispersed inside the macro-porous PTFE material was significantly enhanced by adding macro-porous alumina into the PTFE matrix. The enhanced textural properties of the macro-porous PTFE material where V<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>\/TiO<jats:sub>2<\/jats:sub>\n was uniformly dispersed proved the facilitated diffusion of combustion exhaust gas into the PTFE material.<\/jats:p>","DOI":"10.1166\/jnn.2021.19439","type":"journal-article","created":{"date-parts":[[2021,3,14]],"date-time":"2021-03-14T04:34:06Z","timestamp":1615696446000},"page":"4537-4543","source":"Crossref","is-referenced-by-count":2,"title":["Synthesis of Macro-Porous De-NO<sub>x<\/sub> Catalysts for Poly-Tetra-Fluoro-Ethylene Membrane Bag Filter"],"prefix":"10.1166","volume":"21","author":[{"given":"Byung Chan","family":"Kwon","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, 280 Daehak-ro, Gyeongsan, Gyeongbuk, 38541, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dohyung","family":"Kang","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, 280 Daehak-ro, Gyeongsan, Gyeongbuk, 38541, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, 280 Daehak-ro, Gyeongsan, Gyeongbuk, 38541, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"No-Kuk","family":"Park","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, 280 Daehak-ro, Gyeongsan, Gyeongbuk, 38541, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jang Hun","family":"Lee","sequence":"additional","affiliation":[{"name":"Korea Dyeing & Finishing Technology Institute, 92 Dalseocheon-ro, Seo-gu, Daegu, 41706, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Yeon","family":"Hwang","sequence":"additional","affiliation":[{"name":"Institute for Advanced Engineering, 175-28 Goan-ro, 51 Beon-gil, Baegam-myeon, Cheoin-gu, Yongin-si, Gyeonggi-do, 17180, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Myoung Jo","family":"Seo","sequence":"additional","affiliation":[{"name":"Micro-One Co.
