Pt/TiO2 sensitized by the cheap and organic ortho-dihydroxyl-9,10-anthraquinone dyes, such as Alizarin and Alizarin Red, achieved a TON of approximately 10 000 (TOF > 250 h(-1) for the first ten hours) during >80 hours of visible light irradiation (>420 nm) for photocatalytic hydrogen evolution when triethanolamine was used as the sacrificial donor. The stability and activity enhancements can be attributed to the two highly serviceable redox reactions involving the 9,10-dicarbonyl and ortho-dihydroxyl groups of the anthracene ring, respectively.
采用廉价的有机邻二羟基蒽醌染料（如茜素和茜素红）敏化的 Pt/TiO2，在可见光照射（>420nm）下，以三乙醇胺为牺牲供体，进行超过 80 小时的光催化析氢反应时，TON 约为 10000（前 10 小时的 TOF > 250 h-1）。稳定性和活性的提高可归因于分别涉及蒽环 9,10-二羰基和邻二羟基的两个非常有用的氧化还原反应。
