High-performance Förster resonance energy transfer-based dye-sensitized photocatalytic H2 evolution with graphene quantum dots as the homogeneous energy donor

Abstract

A high-performance dye-sensitized photocatalytic H2 evolution system was developed based on Förster resonance energy transfer (FRET) by employing water-soluble and highly photoluminescent N,S codoped graphene quantum dots (NSGQDs) as the homogeneous energy donor, erythrosin B (ErB) as the sensentizing dye, and platinum nanoparticles (Pt NPs) as the catalyst. NSGQDs absorbed high-energy photons that undergo FRET to transfer the excitation energy to the sensitizing ErB for maximizing light absorption and also served as an electron transfer and loading matrix of Pt NPs for accelarating the electron transfer; as a result, the ErB-sensitized NSGQD-Pt system afforded much higher H2 evolution activity than the NSGQD-free dye-sensitized system.
