A supramolecular single-site photocatalyst based on multi-to-one Förster resonance energy transfer

A multi-to-one supramolecular photocatalyst is fabricated by aqueous electrostatic self-assembly of multiple graphene quantum dot (GQD) antennas onto a single-Pt-site porphyrin unimolecular micelle (PtTHPD-UM) catalytic center. Light energy is transferred from GQDs to PtTHPD-UM to catalyze water splitting into hydrogen up to 57 190 μmol g(Pt)−1 h−1 under visible light.
