Indoor　formaldehyde　(HCHO)　pollution　has　become　a　serious　issue　to　threaten　human　health.　Therefore,　it　is　urgent　to　develop　long-term　and　efficient　HCHO　removal　materials　and　technology　with　low　energy　consumption.　In　this　study,　the　MnOx　was　deposited　in-situ　by　hydrothermal　synthesis　on　the　hydrolyzed　PI　fibers.　By　harvesting　the　kinetic　energy　of　wind,　triboelectric　charges　and　electric　field　are　generated　between　MnOx-PI　and　nylon　fibers.　The　employment　of　triboelectric　charges　on　the　catalyst　is　an　effective　way　to　increase　conversion　rates　of　O*,　which　may　help　to　accelerate　the　decomposition　of　intermediates,　enhance　efficiency,　and　enlarge　the　life　of　the　catalyst.　As　a　result,　during　the　static　testing,　the　HCHO　removal　efficiency　reached　92.4%　of　MnOx-PI-1.0　h-nylon　within　1100　mins　at　room　temperature,　which　was　much　higher　than　that　of　the　MnOx-PI-1.0　h　sample　(56.3%).　In　addition,　the　removal　efficiency　of　the　MnOx-PI-2.0　h-nylon　remained　above　95%　during　the　48-hours　dynamic　test.　The　present　study　provides　a　new　route　to　achieve　long-term　efficient　removal　of　HCHO　in　the　indoor　environment　and　extended　the　application　for　the　nano-triboelectric　in　the　catalytic　field.　©　2020
