Controlled deposition and enhanced visible light photocatalytic performance of Pt-modified TiO2 nanotube arrays

- Pt nanoparticles were deposited onto TiO2 NTAs by UV light photoreduction method.
- Uniform distribution of nanoparticles was achieved by controlling deposition.
- 3 Pt/TiO2 NTAs show 84.27% degradation rate after visible light irradiation.
- The kinetic constant of 3 Pt/TiO2 NTAs is 0.01493 min−1.
