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.
通过将多个石墨烯量子点（GQD）天线在水相中静电自组装到单铂位点卟啉单分子胶束（PtTHPD-UM）催化中心上，制备了一种多对一的超分子光催化剂。在可见光下，光能从GQD转移到PtTHPD-UM，以催化水分解产生氢气，产氢速率高达57190 μmol g(Pt)-1 h-1。
