Abstract：

According　to　a　stepwise　adsorption　approach,　TiO2　NT　photoanode　was　co-sensitized　with　Eosin　Y　and　carbon　dots　for　photoelectrochemical　water　splitting.　The　adsorption　amount　of　Eosin　Y　in　co-sensitized　samples　increases　due　to　the　presence　of　carbon　dots　regardless　of　co-sensitization　sequence.　The　absorbance　of　Eosin　Y/carbon　dots/TiO2　NT　in　visible　light　region　is　stronger　than　that　of　carbon　dots/Eosin　Y/TiO2　NT,　while　carbon　dots/Eosin　Y/TiO2　NT　exhibits　higher　photocurrent　density　and　hydrogen　production　rate.　Based　on　the　shortest　electron　transport　time,　the　electron　diffusion　coefficient　in　carbon　dots/Eosin　Y/TiO2　NT　electrode　is　up　to　14.94　x　10(-19)cm(2)s(-1).　A　favorable　energy　levels　alignment　dominates　in　carbon　dots/Eosin　Y/TiO2　NT,　which　can　further　account　for　enhancement　in　charge　transfer.　(C)　2017　Hydrogen　Energy　Publications　LLC.　Published　by　Elsevier　Ltd.　All　rights　reserved.
