We　report　the　controllable　electrophoretic　fabrication　of　highly　robust,　efficient,　and　benign　photoelectrocatalysts　based　on　graphene-quantum-dot　sensitized　TiO2　nanotube　arrays.　Their　catalytic　activities　under　visible-light　irradiation　remain　steady　for　continuous　cycles　(400　min)　with　a　negligible　decrease,　whereas　CdS　and　CdSe　sensitized　TiO2　nanotube　arrays　show　a　high　cycling　instability　due　to　serious　photooxidization.
