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.

以石墨烯量子点为均质供体 的高性能基于Förster共振能量转移的染料敏化光催化H ₂演化†

基于水溶性和高度光致发光的N，S共掺杂石墨烯量子点（NSGQDs）作为均相能量供体，赤藓红B（Ferster共振能量转移（FRET）），开发了一种高性能的染料敏化光催化H ₂析出体系。 ErB）作为敏化染料，铂纳米颗粒（Pt NPs）作为催化剂。NSGQDs吸收经过FRET的高能光子，以将激发能量转移到敏化ErB上，以使光吸收最大化，并且还充当Pt NPs的电子转移和负载矩阵，以加速电子转移；结果，ErB致敏的NSGQD-Pt系统比不含NSGQD的染料致敏系统具有更高的H ₂释放活性。
