Bimetallic plasmonic nanostructures : synthesis and light-induced applications
For my final year project, I utilized a seed-mediated method to produce silver nanoparticles in solution form and ultimately obtain silver nanoprisms. Subsequently, I coated a layer of gold for the shell (Ag@Au) due to gold’s highly stable and unreactive nature to preserve it. Lastly, the Ag@Au core...

| description | For my final year project, I utilized a seed-mediated method to produce silver nanoparticles in solution form and ultimately obtain silver nanoprisms. Subsequently, I coated a layer of gold for the shell (Ag@Au) due to gold’s highly stable and unreactive nature to preserve it. Lastly, the Ag@Au core-shell is further coated with silicon dioxide and titanium dioxide (Ag@Au@SiO2) and (Ag@Au@TiO2).
My project will focus on the oxidation of the methylene blue (MB) dye due to the reduction of the adsorbed oxygen into reactive species that was caused by the photo-catalytic reaction of the hot electrons that went into conduction band of Titanium Dioxide.
The UV spectrum will also be studied and its effectiveness will be highlighted to show the oxidation of the MB dye due to the descending peak intensity. The results would also be compared to other different variables such as the control MB, Ag nanoprism and Ag@Au core-shell and Ag@Au@SiO2/TiO2 nanostructures in the UV spectrum. |
