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

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
