Abstract：

Fe-doped　cadmium　sulfide　was　prepared　by　hydrothermal　method　in　aqueous　solution　using　cadmium　nitrate,　ferric　nitrate　and　thiourea　as　raw　materials.　The　samples　were　characterized　by　SEM,　XRD,　EDS　and　XPS.　The　photocatalytic　degradation　of　methylene　blue　(MB)　in　aqueous　solution　was　used　as　a　target　reaction　to　evaluate　their　photocatalytic　activity.　The　experimental　results　show　that　the　reaction　temperature　has　a　great　effect　on　the　morphology　of　cadmium　sulfide,　and　spherical,　flowerlike,　clustered　and　rodlike　cadmium　sulfide　are　obtained　in　various　reaction　temperatures.　Among　them,　the　photocatalytic　activity　of　flowerlike　CdS　is　observed　to　be　better　than　other　CdS　materials.　The　XRD　indicates　that　Fe-doped　cadmium　sulfide　is　hexagonal　crystal　structure　when　the　reaction　temperature　is　160.　The　experimental　results　also　indicate　that　Fe-doped　can　obviously　improve　the　photocatalytic　activity　of　cadmium　sulfide　and　when　the　doping　ratio　of　Fe　to　Cd　is　1:10,　the　photocatalytic　effect　is　the　best　of　all.　©　2017,　Journal　of　Materials　Engineering.　All　right　reserved.
