摘要：

In　order　to　enhance　the　photocatalytic　reaction　rate　of　formaldehyde,　the　photocatalytic　technology　was　combined　with　active　carbon　adsorption　technology.　Based　on　the　fastness　and　the　higher　activity　of　TiO2　film,　the　transfer　of　HCHO　to　the　surface　TiO2　film　was　enhanced　for　the　adsorption　of　active　carbon　and　the　local　HCHO　concentration　on　the　surface　of　TiO2　film　was　increased.　The　experimental　results　shown　that　the　photocatalytic　reaction　rate　of　HCHO　was　improved　and　the　adsorption　saturation　of　active　carbon　was　delayed,　so　the　life　of　TiO2　film　was　prolonged.　From　above　results　it　can　conclude　that　the　combination　of　activated　carbon　and　photocatalytic　technology　is　an　application　future　of　photocatalytic　technology.
