Abstract

An efficient green oxidative synthesis was achieved through the development of a bi-functional {FeMo₆}⊂[Ru(N^N)₃@Q-COF] photocatalyst. This catalyst integrates a Ru(N^N)₃ photosensitizer, a stable quinoline-based covalent organic framework (COF), and Anderson polyoxometalates (POMs) via coordination and electrostatic interactions. The combination enhances light absorption, charge transfer, Lewis acid activity, and substrate enrichment within a confined nano-channel environment. Compared to individual catalytic systems, this integrated catalyst demonstrates superior efficiency and selectivity in the photocatalytic oxidation of aldehydes to carboxylic acids. Moreover, it shows excellent recyclability, making it a promising platform for sustainable and efficient catalytic processes.
