Abstract：

In2S3/CdIn2S4　heterojunction　microspheres　were　successfully　prepared　by　one-step　hydrothermal　method,　and　then　the　photocatalytic　performances　were　evaluated　by　the　photocatalytic　degradation　of　MO,　AO　and　RhB.　The　consequence　presented　that　the　photocatalytic　activity　of　In2S3/CdIn2S4　was　significantly　higher　than　those　of　In2S3　and　CdIn2S4　catalysts,　which　could　decompose　87%MO,　75%　AO　and　96%　RhB,　respectively.　The　photogenerated　electrons　and　holes　could　be　separated　quickly　over　In2S3/CdIn2S4　heterojunction　microspheres,　drawing　a　conclusion　from　transient　photocurrent　response　and　impedance　test.　The　experiments　captured　by　the　main　active　radicals　showed　that　the　superoxide　radicals　and　holes　played　a　key　irreplaceable　role　in　the　reaction　system.　Meanwhile,　the　stability　is　still　at　a　high　level　after　four　successive　cycles　over　In2S3/CdIn2S4　heterojunction　microspheres.　The　enhancing　activity　can　attribute　to　the　heterojunction,　which　can　contribute　to　the　electron　transfer　and　conclusively　suppress　the　recombination　of　the　electrons/holes　pairs.　In　addition,　a　suitable　energy　band　structure　helps　to　generate　a　large　number　of　photo-generated　electrons,　and　the　combination　of　electrons　and　active　oxygen　ultimately　leads　to　the　enhancement　of　oxidation　ability.　©　2020,　Chemical　Industry　Press　Co.,　Ltd.　All　right　reserved.
