Photoinduced hydrogen production with chlorophyll-platinum nano-conjugated micellar system

Photoinduced hydrogen production with Mg chlorophyll-a (MgChl-a) from spirulina as a visible-light photosensitizer by use of three component system consisting of NADH as an electron donor, methylviologen (MV2+) as electron relay reagent and colloidal platinum as hydrogen production catalyst in cationic surfactant, alkyltrimethyl bromide with different methylene chain length(CH3(CH2)nN(+)(CH3)(3)Br-.(-); n=9, 13 and 15) micellar media is investigated. Consequently, the effective MV2+ photoreduction and hydrogen production system is accomplished using MgChl-a in CH3(CH2)(15)N+(CH3)(3)Br-.(-) micellar media. (c) 2005 Elsevier B.V.
