The　development　of　metal-free　photocatalyst　to　make　maximum　use　of　the　solar　energy　for　photocatalytic　disinfection　is　highly　desired.　Herein,　boron-and　phenyl-codoped　graphitic　carbon　nitride　was　prepared　by　thermal　polycondensation　of　cyanamide　with　3-aminobenzeneboronic　acid　and　applied　as　photocatalyst　to　inactivate　Escherichia　soli　(E.　coli).　The　photocatalysts　exhibited　the　enhanced　light　responsive　range　over　ultraviolet　to　near　infrared　light　and　99.9%　bacteria　could　be　inactivated　within　3　h　with　a　low　concentration　of　photocatalyst　under　the　irradiation　of　simulated　solar　light.　The　disinfection　mechanism　was　studied　by　scavenger　experiments,　indicating　H2O2　was　the　main　reactive　species　for　the　inactivation　of　bacteria.　Finally,　the　photocatalyst　was　deposited　on　the　surface　of　solid　material　and　also　exhibited　strong　disinfection　performance.　Taking　advantage　of　excellent　disinfection　activity　and　low　cytotoxicity,　the　photocatalyst　showed　a　promising　application　in　solar-driven　photocatalytic　disinfection　in　public　place.
