In　this　paper,　efficiency　recovery　of　rare　earth　elements　from　cathode　ray　tubes　(CRT)　waste.　Moreover,　recycled　yttrium　was　also　served　as　raw　material　to　produce　a　low-cost　Y-doped　TiO2　nanosheets　film　with　exposed　{100}　facets.　An　etching/dissolution　growth　mechanism　was　postulated　by　systematically　investigating　the　influence　of　the　reaction　time.　The　synergistic　effect　of　the　Y　dopant　and　the　dominant　{001}　facets　endows　TiO2　nanosheets　film　with　excellent　activity　in　the　photoremoval　of　Methyl　Orange　(MO)　and　Cr(VI).　A　possible　mechanism　of　photoremoval　of　MO　and　Cr(VI)　is　proposed.　This　study　not　only　contributes　to　recycling　methods　for　CRT　waste　but　also　presents　a　new　way　to　prepare　low-cost　sustainable　photocatalytic　materials　using　economically　viable　waste.
