The surface chemical functionalization generally endows gold nanoparticles (Au-NPs) with expanding applications in sensors, medicine and catalysis because of the synergistic effect. In this work, we report a novel strategy for the synthesis of phosphonate functionalized Au-NPs (P-Au-NPs) by using vinylphosphonic acid as the reducing agent and stabilizing agent. The morphology, composition, and structure...
A TiO2 compact layer was coated on fluorine-doped tin oxide (FTO) glass substrate prior to deposition of SnO2 nanocrystalline thin film to suppress backflow of electrons from FTO to the SnO2 nanocrystalline thin film. The resultant thin film was used as a photoelectrode to fabricate dye-sensitized solar cell. For comparison, a SnO2 compact layer was also prepared to discuss the effect of the TiO2...
