Abstract
- This work shows results of our investigation on Ag 3 PO 4 /TiO 2 NTAs photoelectrode photodegradation properties to diclofenac with visible light illumination. The composite photoelectrode has been synthesized by ultrasound-precipitation strategy and characterized through scanning electrons microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). In addition, photoelectrochemical and visible photocatalytic activity properties of as-prepared samples were investigated to prove the fact. Compared with pure TiO 2 NTAs, Ag 3 PO 4 /TiO 2 NTAs photoelectrode possesses the enhancement of light absorbance in the visible region and a lower recombination rate of photogenerated electron–hole pairs, so that it performed a better visible light photocatalytic property. Additionally, prepared Ag 3 PO 4 /TiO 2 NTAs photoelectrode has well recyclability. On the basis of electrochemical, fluorescence spectra and photoluminescence, the photocatalytic performance enhancement mechanism for Ag 3 PO 4 /TiO 2 NTAs was put forward. [ABSTRACT FROM AUTHOR]
