Organic　pollutant,　originating　from　both　industry　and　domestic　waste,　has　been　greatly　threatening　the　waters　all　over　the　world.　Micromotors,　integrated　with　photocatalysis,　provide　a　promising　solution　to　this　critical　challenge.　In　this　work,　by　taking　advantage　of　the　positive　motion　of　the　micromotors　and　visible　light　response　of　photocatalysis,　we　fabricated　BiOI　microspheres　based　micromotors　and　applied　them　into　organic　pollutant　removal　in　water.　The　motion　characterization　and　dye　degradation　tests　demonstrate　that　＇on-the-fly＇　water　remediation　is　realized　under　visible　light　irradiation.　What＇s　more,　with　the　iron　oxide　nanoparticles　embedded,　the　micromotors　are　recycled　using　magnet　and　reused　in　organic　pollutant　degradation.　©　2019　Elsevier　B.V.
