Abstract:	A photoinduced-H₂ production system, coupling cellulose degradation by cellulase and glucose dehydrogenase (GDH) and H₂ production with colloidal Pt as a catalyst using the visible light-induced photosensitization of Mg chlorophyll a, has been developed. When the sample solution containing methylcellulose, cellulase, GDH, NAD⁺, Mg chlorophyll a, Methyl viologen and colloidal Pt was irradiated, continuous H₂ production was observed. The amount of H₂ production was about 12 mol after 4 h irradiation.

Keywords:	biomass cellulase cellulose H₂ production Mg chlorophyll a visible light
