Efficient plansmonic hot-electron generation for H2O2 Synthesis

Plasmonic metal nanostructures can absorb visible light and generate hot electrons that facilitating further electrochemical reactions such as H2O2 synthesis. A metal–insulator–metal structure of Au nanoparticles on a ZnO/TiO2/Al film is designed and studied. JCMsuite was used to determine the best dielectric spacer thickness to maximize the Au absorption.
