Abstract

A facile sensitization route was adopted to construct well-dispersed Ag nanoparticles on TiO2 nanotube arrays (TNAs) which were prepared by the anodization method. The Ag content loaded on the arrays was controlled by changing the concentration of AgNO3 solution. Ag/TiO2 nanotube arrays (Ag/TNAs) were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) pattern, UV–vis spectroscopy and photoluminescence (PL) spectroscopy. The effect of Ag content on the photoelectrochemical property of TNAs was studied. It showed significant enhancement in photoelectrochemical property compared to pure TNAs.
