Abstract
A photoinduced hydrogen production system, coupling cellulose hydrolysis by cellulase and glucose dehydrogenase (GDH) and hydrogen production with platinum nanoparticles as a catalyst using the visible light photosensitization of Mg chlorophyll-a (Mg Chl-a) from Spilurina, has been developed. When the sample solution containing cellulose derivative (methylcellulose), cellulase, nicotinamide adenine dinucleotide (NAD+), Mg Chl-a, methyl viologen (MV2+, an electron carrier reagent), and platinum nanoparticles was irradiated, continuous hydrogen production was observed with irradiation time. The amount of hydrogen production was about 12 μmol after 4 h irradiation.
