Abstract

We investigated the CT process between a 4-mercaptobenzoic acid (4-MBA) monolayer and TiO₂ NPs under high pressure using surface-enhanced Raman scattering (SERS). Employing the CT enhancement mechanism of semiconductors, we explore the CT process and explain how the pressure affects the process in the 4-MBA@TiO₂ system.
