Photocatalytic generation of hydrogen by using oleic acid-capped CdS, CdSe, and CdS(0.75)Se(0.25) alloy nanocrystals (quantum dots) has been investigated under visible-light irradiation by employing Na(2)S and Na(2)SO(3) as hole scavengers. Highly photostable CdS(0.75)Se(0.25) alloy nanocrystals gave the highest hydrogen evolution rate (1466 μmol h(-1) g(-1)), which was about three times higher than that of CdS and seven times higher than that of CdSe.
通过使用油酸包覆的硫化镉（CdS）、硒化镉（CdSe）和硫化镉（0.75）硒（0.25）合金纳米晶体（量子点）在可见光照射下利用硫化钠（Na₂S）和亚硫酸钠（Na₂SO₃）作为空穴清除剂进行光催化产氢的研究。具有高光稳定性的硫化镉（0.75）硒（0.25）合金纳米晶体产生了最高的析氢速率（1466 μmol h⁻¹ g⁻¹），这大约是硫化镉的三倍，是硒化镉的七倍。
