Abstract：

Polyacrylonitrile　(PAN)　fiber　was　modified　with　NH2OH　and　FeCl3　aqueous　solution　to　prepare　Fe　(III)-amidoximated　PAN　fiber　complex　(Fe-AO-PAN),　which　was　characterized　using　FTIR,　XPS,　and　DRS　respectively.　Then　the　photocatalytic　activity　of　Fe-AO-PAN　was　evaluated　in　degradation　of　a　typical　organic　dye,　Rhodamine　B　in　the　presence　of　H　2O2　under　visible　light　irradiation.　The　results　indicated　that　Fe　(III)　ions　can　be　fixed　on　the　surface　of　Fe-AO-PAN　by　the　coordination　of　Fe　(III)　ions　with　the　amino　nitrogen　atoms　and　hydroxyl　oxygen　atoms　of　the　amidoximation　groups.　Fe-AO-PAN　is　found　to　be　activated　in　the　visible　light　region.　Moreover,　Fe-AO-PAN　shows　the　catalytic　activity　for　dye　degradation　at　pH=6.0　in　the　dark,　and　can　be　significantly　enhanced　under　visible　light　irradiation.　©　2009　IEEE.
