文摘
- •
Pt-modified mixed phase TiO2 hollow nanofibers photocatalysts were prepared.
- •
The band gap of TiO2 HNFs decreased from 3.09 down to 2.77 eV with 2 wt.% Pt loading.
- •
Pt/TiO2 HNFs exhibited enhanced visible-light photocatalytic activity for the degradation of Orange II.
- •
The stability of Pt/TiO2 HNFs and possible degradation mechanism were investigated.
- •
O2− radicals were the main reactive oxygen species for Orange II degradation.
