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 micromol, 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.
研究了以螺旋藻中的叶绿素镁-a作为可见光和近红外光光敏剂，利用由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和胶体铂作为产氢催化剂组成的三组分体系进行光致产氢。照射4小时后，叶绿素镁-a和作为叶绿素人工模型化合物的四苯基卟啉镁（MgTPP）的产氢量分别约为2.7微摩尔和1.8微摩尔。当照射近红外光时，产氢量几乎没有变化。因此，利用叶绿素镁-a建立了有效的胶体铂可见光和近红外光诱导产氢体系。
