 This research proposes a novel method to create stable heterostructures composed of covalent organic frameworks, COFs, and titanium dioxide, TiO2. By modifying the COFs' pore wall with metal precursors, the researchers were able to induce site-specific nucleation of TiO2 nanodots within the COFs. These nanodots are then grown into the COFs matrix, resulting in enhanced catalytic activity due to stronger NTO bonds. Density functional theory calculations show that this modification leads to increased energy transfer from the COF to the TiO2 nanodot, which further enhances the catalytic activity. This study demonstrates the potential of using COFs as a platform for creating stable heterostructures with TiO2 nanodots for efficient artificial photosynthesis.
