Abstract
To decompose dye in aqueous solution, Pd nanoparticle-decorated TiO2 nanotube photocatalysts were fabricated through electrochemical anodization and photoreduction processes. Morphological and surface characterization of the TiO2/Pd heterojunction photocatalyst, as well as photoelectrochemical behaviors, were investigated by X-ray diffraction, UV/Vis diffuse reflectance and photocurrent response. It was found that the precipitated..... More

                        
Synthesis and Characterization of ZnO/TiO2 Photocatalyst Decorated with PbS QDs for the Degradation of Aniline Blue Solution
Jong-Ho Lee, Hong-Joo Ahn, Jeong-Il Youn, Young-Jig Kim, Su-Jeong Suh, Han-Jun Oh
Korean J. Met. Mater. 2018;56(12):900-909.   Published online 2018 Dec 5
DOI: https://doi.org/10.3365/KJMM.2018.56.12.900

Abstract
A ZnO/TiO2 photocatalyst decorated with PbS quantum dots (QDs) was synthesized to achieve high photocatalytic efficiency for the decomposition of dye in aqueous media. A TiO2 porous layer, as a precursor photocatalyst, was fabricated using micro-arc oxidation, and exhibited irregular porous cells with anatase and rutile crystalline structures. Then, a..... More
