The reactivity of a heterogeneous rhodium(III) and ruthenium(II) complex-functionalized TiO 2 nanoparticle (NP) system is reported. The ruthenium and rhodium metal complexes work in tandem on the TiO 2 NPs surface to generate H 2 through water reduction under simulated and normal sunlight irradiation. The functionalized TiO 2 NPs outperformed previously reported homogeneous systems in turnover number (TON) and frequency (TOF). The influence of individual components within the system, such as pH, additive, and catalyst, were tested. The NP material was characterized using TGA-MS, 1 H NMR spectroscopy, FTIR spectroscopy, solid absorption spectroscopy, and ICP-MS. Gas chromatography was used to determine the reaction kinetics and recyclability of the NP-supported photocatalyst.
