title: Visible light induced hydrogen production with Mg chlorophyll-a from spirulina and colloidal platinum.
abstract: Photoinduced hydrogen production with Mg chlorophyll-a from spirulina as a visible 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 evolution catalyst was investigated. By the addition of NADPH, the photostability of Mg chlorophyll-a was increased. The effective visible-light induced hydrogen production system with colloidal platinum was established using Mg chlorophyll-a.
