Title
Electrodeposition preparation of Ag loaded N-doped TiO2 nanotube arrays with enhanced visible light photocatalytic performance
Abstract

Ag nanoparticles loaded N-doped TiO2 nanotube arrays (Ag/N-TNTs) were successfully fabricated by an electrodeposition method. The Ag/N-TNTs were characterized using field-emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), and UV–vis diffusion reflection spectroscopy (UV–vis DRS). The average photocurrent density and the photocatalytic degradation efficiency of the Ag/N-TNTs obtained for the degradation of Acid Orange II(AO-II)are 6 times and 6.8 times higher than those of annealed TiO2 nanotube arrays (A-TNTs), respectively. This bestows the Ag/N-TNTs as a promising photocatalytic material for organic pollutant degradation under visible light.
