Formaldehyde　(HCHO)　is　one　of　the　most　common　indoor　pollutants.　Long　time　exposure　to　the　environment　with　HCHO　concentration　above　0.1mg/m(3)　can　cause　harm　to　human　body.　In　order　to　remove　HCHO　efficiently,　The　TiO2/AC　network　film　was　prepared　by　loading　nanometer　particle　TiO2　on　the　surface　of　activated　carbon.　The　photocatalytic　degradation　of　gaseous　HCHO　was　performed　by　TiO2/AC　network　film　under　the　irradiation　of　UV365nm,　UV254nm　and　UV254+185nm,　respectively.　The　results　show　that　the　adsorption　of　AC　network　and　byproduct　ozone　(O-3)　oxidation　simultaneously　can　promote　the　degradation　of　the　HCHO;　under　the　illumination　of　UV254+185nm,　HCHO　can　be　degraded　more　effectively.　The　produced　ozone　can　also　be　degraded　below　0.214　mg/m(3)　that　are　required　by　Chinese　indoor　air　quality　standard.　(C)　2015　The　Authors.　Published　by　Elsevier　Ltd.
