Novel CdSe quantum dot (QD)-sensitized Au/TiO2 hybrid mesoporous films have been designed, fabricated, and evaluated for photoelectrochemical (PEC) applications. The Au/TiO2 hybrid structures were made by assembly of Au and TiO2 nanoparticles (NPs). A chemical bath deposition method was applied to deposit CdSe QDs on TiO2 NP films with and without Au NPs embedded. We observed significant enhancements...
Nearly monodisperse spherical amorphous Se colloids are prepared by the dismutation of Na2SeSO3 solution at room temperature; by altering the pH of the solution, amorphous Se colloid spheres with sizes of about 120 nm, 200 nm, 300 nm, and 1 µm can be obtained. Se@Ag2Se core/shell spheres are successfully synthesized by using the obtained amorphous Se (a-Se) spheres as templates, indicating the potential...
