Removal　of　dust　and　NOx　from　flue　gas　is　highly　significant　for　air　pollution　control,　and　integration　of　these　two　functions　in　one　unit　can　greatly　improve　process　efficiency.　In　this　study,　a　functional　catalytic　bag-filter　material　(CBFM)　was　fabricated　from　commercial　PTFE　felt　and　cheap　catalyst　V2O5-WO3/TiO2　via　a　simple　immersion-fixation　procedure.　The　attachment　of　catalysts　on　PTFE　was　confirmed,　and　the　material　properties　of　CBFM　of　various　loadings　were　determined.　Their　denitration　and　dedusting　performances　were　investigated　individually　in　lab-scale　experiments.　Compared　to　the　original　PTFE,　CBFMs　exhibited　superior　denitration　activities,　which　were　positively　correlated　with　temperature　(60–90%　under　150–210　°C)　and　negatively　correlated　with　filtration　velocity　(50–90%　under　0.5–0.9　m　min−1).　On　the　other　hand,　introduction　of　catalysts　in　PTFE　felt　did　not　compromise　its　filtration　efficiency,　and　almost　complete　dust　removal　was　achieved.　A　simplified　kinetic　model　was　developed　based　on　Eley-Rideal　mechanism,　to　correlate　the　materials＇　denitration　efficiency　with　various　operational　conditions.　The　model＇s　accuracy　was　verified　in　both　lab　and　pilot　environments,　where　real　flue　gas　from　a　waste　incineration　plant　was　treated　with　a　scaled-up　CBFM.　In　a　six-day　continuous　test,　the　CBFM　maintained　＞70%　NO　removal　and　＞99.8%　dust　removal,　confirming　its　stability　and　applicability　in　industrial　settings.　Therefore,　this　study　offers　a　low-cost　and　functional　bi-functional　filter　material　capable　of　efficient　simultaneous　dedusting/denitration,　as　well　as　a　simple　and　practical　procedure　for　its　manufacture.　In　addition,　the　kinetic　model　could　be　applied　to　speed　up　production　and　process　optimization,　and　direct　future　application　of　similar　materials　in　real　environments.　©　2023　Elsevier　Ltd
