Abstract：

To　improve　the　photoelectrochemical　properties　of　TiO2,　an　approach　of　codoping　is　introduced　to　simultaneously　tailor　the　band　gap　and　control　the　life　time　of　photoexcited　electron–hole　pairs.　Molybdenum　doping　is　used　to　extend　the　optical　absorption　of　TiO2　while　silver　inclusion　in　the　molybdenum-doped　TiO2　network　improves　the　separation　between　the　photogenerated　carriers　leading　to　improved　photodegradation　response.　X-ray　photoelectron　spectroscopy　(XPS)　confirmed　the　existence　of　dopant　atoms　in　the　bulk　lattice　and　the　codoped　sample　exhibits　enhanced　photodegradation　performance　compared　to　monodoped　samples.　With　less　structure　modifications　and　stable　structure,　the　silver　molybdenum　codoped　TiO2　highly　improve　the　wide　functionalities　of　TiO2　in　photoelectrochemical　applications.　©　2017,　The　Minerals,　Metals　&　Materials　Society.
