AB  - The surface modification of commercial TiO2 powder with catecholate-type ligand Tiron (TIR) leads to the formation of the interfacial charge transfer complex (ICT) absorbing in the visible spectral range. The estimated band gap energy of the ICT complex (Eg = 2.2 eV) by density functional theory (DFT) calculations agrees with experimental measurements. The surface-modified TiO2 with TIR has enhanced sorption capacity towards Pb2+ ions compared to the pristine one due to the presence of free sulfonate groups. Our attempt to reduce Pb2+ ions to metallic form failed. The TiO2-based ICT complex with TIR can serve as an efficient sorbent to remove Pb2+ ions from the solution without the ability to recover them in metallic form in a photo-driven catalytic process. The photocatalytic ability of the ICT complex to induce oxidation reactions is significantly improved since the complete degradation of organic dye methyl orange occurs under exclusive excitations with visible light photons.

AB  - The interfacial charge transfer (ICT) complex formation is a simple procedure to bring optical absorption of widebandgap oxide materials in the visible spectral range, crucial for enhancing their use in photo-driven reactions. The optical absorption of the prepared ICT complexes between ZnO and five different colorless benzene derivatives is red-shifted compared to pristine ZnO nanopowder. The density functional theory (DFT) calculations provided realistic energy level alignment in hybrid systems. Also, the DFT-calculated infrared spectra support the binding structures derived based on experimental measurements of free and adsorbed ligands onto ZnO surfaces. The photocatalytic performance of prepared hybrids was evaluated using photocatalytic hydrogen generation in the water-splitting reaction. The ZnO nanopowders modified with catechol and caffeic acid have over 50% higher hydrogen production rate than pristine ZnO, displaying steady hydrogen production under long-run working conditions.
