本研究报告使用水溶性S3-cap-CdSe量子点敏化NiO作为光电阴极，[Co（bdt）2]−（bdt = 1，2-benzenedithiolate）或Ni（DHLA）x（DHLA=二氢硫辛酸的阴离子）络合物作为H2形成催化剂。NiO-S3-cap-CdSe/[Co（bdt）2]−体系产生的H2的转换频率为3000/CdSe mol·h。该系统的法拉第效率基本上是定量的。两种体系均稳定16 h以上。
The present study reports photelectrochemical H2 evolution using a water-solubilized S3-cap-CdSe quantum dot-sensitized NiO as the photocathode and either [Co(bdt)2]− (bdt =1,2-benzenedithiolate) or Ni(DHLA)x (DHLA= the anion of dihydrolipoic acid) complex as the H2-forming catalyst. The NiO-S3-cap-CdSe/[Co(bdt)2]− system produces H2 with a turnover frequency of 3000 per CdSe mol·h. Faradaic efficiency for this system is essentially quantitative. Both systems are stable for more than 16 h.
