Decoration of Ti/TiO2 nanotubes with Pt nanoparticles for enhanced UV-Vis light absorption in photoelectrocatalytic process

Pt nanoparticles were decorated on TiO2 nanotube arrays (TiO2NTs) by cathodic deposition. These nanoparticles were uniformly distributed, highly separated and spaced all over TiO2NT surface to shorten ...
