研究了以螺旋藻叶绿素a镁为可见光和近红外光敏剂，以还原型烟酰胺腺嘌呤二核苷酸磷酸（NADPH）作为电子供体，甲基紫精作为电子中继试剂，胶体铂作为制氢催化剂的三组分体系进行光诱导制氢。照射 4 小时后，叶绿素-a 镁和叶绿素人工模型化合物 MgTPP 的产氢量约为 分别为 2.7 和 1.8 μmol。当照射近红外光时，观察到氢气产量几乎没有变化。因此，利用叶绿素-a 镁建立了有效的可见光和近红外光诱导胶体铂制氢系统。
Photoinduced hydrogen production with Mg chlorophyll-a from Spirulina as a visible and near-IR light photosensitizer by use of three component system consisting of nicotineamide adenine dinucleotide phosphate, reduced form (NADPH) as an electron donor, methylviologen as electron relay reagent and colloidal platinum as hydrogen production catalyst was investigated. After 4 h irradiation, the amount of hydrogen production with Mg chlorophyll-a and MgTPP, which was artificial model compound for chlorophyll, were c.a. 2.7 and 1.8 μmol, respectively. When the near-IR light was irradiated, little change of hydrogen production was observed. Thus, the effective visible and near IR light induced hydrogen production system with colloidal platinum was established using Mg chlorophyll-a.
