This study focuses on enhancing the photocatalytic activity of TiO₂ by utilizing localized surface plasmon resonance (LSPR) of Au nanoparticles. Previous research confirmed that the TiO₂/Au/TiO₂/Au (IMIM) multilayer structure exhibits high photocatalytic activity, but its enhancement mechanism remained unclear. In this study, TiO₂/Au (IM), Au/TiO₂/Au (MIM), and IMIM structures were fabricated and compared to elucidate the mechanism behind the photocatalytic activity improvement of the IMIM structure.
