Photoresponse performance of Au (nanocluster and nanoparticle) TiO2: Photosynthesis, characterization and mechanism studies
Year: 2024
Type: article
Abstract: In this study, gold (Au), nanoclusters (NC) and heterogeneous titanium dioxide (TiO 2 ) were successfully synthesized by low-temperature photoelectron spectroscopy . The chemical structure of Au-TiO 2 was characterized by XRD , EDX , XPS and HR-TEM. Optical properties were evaluated using PL and UV–Vis, and electrical properties were evaluated using CV , CP, UPS and EIS parameters. The results showed that Au nanocluster (NCs) were converted into Au nanoparticles (NPs) during high sunlight, and the transfer mechanism was examined. In addition, the produced nanoparticles can form a Schottky barrier with TiO 2 , which affects the band structure . Moreover, the simultaneous synthesis of nanoparticles and nanoclusters adds an extra dimension to the understanding of the photoelectronic behavior of structured photoelectrodes . Moreover, this research shows that good control of the photography process can result in more photos. This improvement is related to several factors, including the plasmonic field and coupling line bending.
