Very recently, Matsuoka and co-workers have studied the titanium based MIL-125 that has been
amino-functionalised, termed Ti-MOF-NH2. Figure 3 depicts the underlying mechanism being proposed for the hydrogen production reaction using aqueous solution containing TEOA (triethanolamine), which acts as a sacrificial electron donor under visible-light irradiation.
It was proposed that the water splitting mechanism proceeds through photon absorption by the organic linker (acts as an antenna), which subsequently transfers electrons to the catalytically active inorganic Ti-oxo clusters where the protons (Hz) are finally reduced to form molecular hydrogen, H2. Additionally, it can be seen in Fig. 4 that the photocatalytic performance of TiMOF-NH2 can be substantially enhanced by depositing small quantities of platinum (up to 2 wt-%Pt) onto the parent MOF material.
