- •
Provide insights for decontaminating toxic pharmaceutical agents.
- •
TiO2 fibers with 38 wt% rutile have the optimal photocatalytic performance.
- •
Surface area, grain size and phase composition affect the photocatalytic activity.
- •
An optimal grain size balances e−/h+ recombination rate and charge diffusion rate.
- •
Higher rutile fraction will result in larger grain size and lower surface area.
