Tunable Plasmon-induced Charge Transport and Photon Absorption of Bimetallic Au/Ag Nanoparticles on ZnO Photoanode for Photoelectrochemical Enhancement under Visible Light

This thesis examines the fabrication process of noble metal bimetallic Au/Ag nanoparticles via solid-state thermal dewetting under different annealing temperature and composition ratio of bimetallic nanoparticles. Also, this thesis delivers a general approach to understand the plasmon-induced charge interaction, hence photochemistry of Au/Ag bimetallic nanoparticles/semiconductor photoanode by determining the optimal composition ratio of 0.25 Au/Ag bimetallic nanoparticles which is capable of exploiting the enhanced electrical conduction and localized surface plasmon resonance effect for photoelectrochemical water splitting.
