Water Photolysis Using Light-Harvesting Function of Chlorophyll Solubilized in Micellar Media

Abstract

Photoinduced hydrogen production with the system consisting of Mg chlorophyll-a (MgChl-a) from spirulina as a visible light photosensitizer, NADH, methylviologen (MV²⁺) and colloidal platinum in trimethyl alkyl bromide (CH₃(CH₂)_nN(CH₃)₃⁺ . Br-; n=8, 12 and 14) micellar media was investigated. Consequently, the effective MV²⁺ photoreduction and hydrogen production systems were accomplished using MgChl-a in CH₃(CH₂₁₄N(CH₃)₃⁺ . Br^- micellar media.
