本文研究了以四羧酸酞菁锌为光敏剂的新型光催化释氢体系。工作中发现,在水溶液中存在有阳离子表面活性剂时,不仅可以减少在光化学反应中非活性的二聚体含量,而且可以促进电荷分离并提高四组分体系的光催化反应效率。简单地讨论了四组分体系释氢反应的机理。
In this paper, a novel photocatalytic hydrogen release system using tetracarboxylic acid zinc phthalocyanine as photosensitizer was studied. It has been found during work that the presence of a cationic surfactant in an aqueous solution not only reduces the amount of inactive dimer in the photochemical reaction but also promotes charge separation and increases the photocatalytic efficiency of the four-component system. The mechanism of hydrogen release reaction of four-component system is briefly discussed.
