Zn Cd1–S quantum dot with enhanced photocatalytic H2-production performance

H2 is an important energy carrier for replacing fossil fuel in the future due to its high density and environmental friendliness. As a sustainable H2-generation method, photocatalytic production by water splitting has attracted much interest. Here, oil-soluble ZnxCd1–xS quantum dot (ZCS QD) with uniform particle size distribution were prepared hot-injection method. However, no H2-production activity was observed ZCS QD hydrophobicity. Thus, converted into water-soluble ligand-exchange The exhibited excellent performance presence of glycerin Ni2+, apparent efficiency 15.9% under irradiation 420 nm light. Further, ∼10.7 times higher than that relative samples conventional co-precipitation This work will inspire design fabrication other semiconductor photocatalysts because exhibits separation photogenerated electron–hole pairs small crystallite size.
