文摘
- •
Hollow sulfated V-doped TS-1 shows superior visible-light responsiveness.
- •
14% cyclohexane conversion and 94% KA-oil selectivity are achieved.
- •
On the tetrahedral Ti4+ sites, cyclohexane is transformed selectively.
- •
V, S codoped TS-1 promotes the oxidation process with high TOF (2.37 h−1).
- •
O
VO4Ti bridging sites in hollow TS-1 are the main active sites.
