文摘
- •
Ag0 loaded on MTN was prepared by a direct in-situ electrochemical method.
- •
The introduction of Ag0 lowers the band gap and increases the number of OV and TSD.
- •
Ag0 acted as an electrons trapper and also a plasmonic sensitizer.
- •
The formation of Ti-O-Ag in 10 wt% Ag-MTN decreased the amount of Ag0, TSD and OV.
- •
5 wt% Ag-MTN gave the highest percentage of photodegradation of 2-CP.
