Photocatalytic performance of TiVOx/TiO2 thin films prepared by bipolar pulsed magnetron sputter deposition
JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B(2017)
摘要
TiO2 films were formed by sputtering, and TiVOx films were deposited by bipolar pulsed magnetron sputtering with pure Ti and V metal targets. The sputtering of V on Ti oxide had little effect on the orientation of the TiO2 (01) plane of the specimen assemblies. The main varying parameter was the vanadium pulse power. Sputtered V is supposed to undergo resputtering, favoring a low deposition rate and small thickness. TiO2 films that were sputtered with a vanadium pulse power of 150W were most effective in the photocatalytic decomposition of methylene blue solution. (C) 2017 American Vacuum Society.
