PREPARATION OF PHOTOCATALYTIC THIN FILMS OF TRICALCIUM PHOSPHATE BY DOPING TITANIUM(IV) ION

摘要

: Thin films of tricalcium phosphate (TCP) with doping Ti(IV) ion were prepared. These prepared films were characterized by XRD, UV-vis transmission, FT-IT (RAS), and wettability. These characterization indicated that phase separation such as TiO_(2) did not occur and that substitution with Ti(IV) occurred at Ca site. Photocatalytic activity was evaluated by methylene blue decomposition, and the results suggested that the activity was enhanced by doping Ti(IV).
