Synthesis of Pore-Wall-Modified Stable COF/TiO₂ Heterostructures via Site-Specific Nucleation for an Enhanced Photoreduction of Carbon Dioxide.

ABSTRACT: Constructing stable heterostructures with appropriate active site architectures in covalent organic frameworks (COFs) can improve the active site accessibility and facilitate charge transfer, thereby increasing the catalytic efficiency. Herein, a pore-wall modification strategy is proposed to achieve regularly arranged TiO₂ nanodots (≈1.82 nm) in the pores of COFs via site-specific nucleation. The site-specific nucleation strategy stabilizes the TiO₂ nanodots as well as enables the controlled growth of TiO₂ throughout the COFs' matrix. In a typical process, the pore wall is modified and site-specific nucleation is induced between the metal precursors and the organic walls of the COFs through a careful ligand selection, and the strongly bonded metal precurso
