Interfacial Charge-Transfer Transitions in TiO2 Nanoparticles Adsorbed with 4-Mercaptobenzenoic Acid: Carboxy versus Thiol Anchor and Adsorbate-to-TiO2 versus TiO2-to-Adsorbate Charge Transfer

Jun-ichi Fujisawa et al.

Summary: The study investigates the surface complex of TiO2 nanoparticles with 4-mercaptobenzoic acid (4-MBA) and finds that 4-MBA adsorbs on TiO2 via the carboxylate group instead of the reported thiol linkage. The absorption band observed in the visible region is attributed to interfacial charge-transfer transitions from the highest occupied molecular orbital (HOMO) of the adsorbed 4-MBA to the conduction band of TiO2, contrasting with the previously reported TiO2-to-adsorbate charge-transfer scheme.
