摘要：
In this study, Pt NCs/TiO2 NTAs photoelectrode was fabricated through anodization process, followed by recycle pulse electrodeposition strategy. Subsequently, physicochemical properties of the resulting samples were studied systematically. Results indicated that Pt NCs/TiO2 NTAs photoelectrode exhibited intense light absorbance both in the UV and visible region, high transient photocurrent density of 0.089 mA cm(-2) and open circuit potential of -0.275 V cm(-2). In addition, 983% of aspirin could be eliminated within 4 h Xenon illumination with the help of +0.4 V potential. Furthermore, it can be concluded that two tentative pathways for PEC degradation of aspirin were proposed and confirmed. (C) 2016 The Korean Society of Industrial and Engineering Chemistry.
