With　increasingly　stringent　environmental　regulations,　the　removal　of　nitrogen-containing　compounds　(NCCs)　from　gasoline　fuel　has　become　a　more　and　more　important　research　subject.　In　this　work,　we　have　successfully　synthesized　TiO　2　/α-Fe　2　O　3　heterogeneous　photocatalysts　with　different　mass　ratios　of　TiO　2　vs.　α-Fe　2　O　3　.　Taking　photocatalytic　denitrification　of　typical　alkali　NCCs,　pyridine,　in　gasoline　fuel　under　visible　light　irradiation　(λ　≥　420　nm)　as　the　model　reaction,　the　TiO　2　/α-Fe　2　O　3　hybrids　have　exhibited　enhanced　photocatalytic　activity　compared　with　pure　TiO　2　and　α-Fe　2　O　3　,　giving　a　pyridine　removal　ratio　of　∼100%　after　irradiation　for　240　min.　The　improved　photocatalytic　performance　can　be　attributed　to　the　integrative　effect　of　the　enhanced　light　absorption　intensity　and　more　efficient　separation　of　photogenerated　electron-hole　pairs.　Importantly,　this　type　of　heterogeneous　photocatalysts　can　be　easily　separate　in　the　reaction　medium　by　an　external　magnetic　field　that　is　very　important　for　industrial　purpose.　In　addition,　major　reaction　intermediates　have　been　identified　by　the　liquid　chromatograph-mass　spectrometer　(HPLC-MS)　and　a　tentative　photocatalytic　denitrification　mechanism　has　been　proposed.　©　2017,　The　Author(s).
