摘要

A biohydrogen production system,has been developed that couples sucrose hydrolysis by invertase and glucose dehydrogenase (GDH) and hydrogen production with a platinum colloid as a catalyst.The system uses the visible light-harvesting function of artificial Zn chlorophyll-a (Zn Chl-a),prepared from Mg Chl-a (obtained from Spilurina).When a sample solution containing sucrose,invertase,nicotinamide adenine dinucreotide (NAD~+),Zn Chl-a,methyl-viologen (MV~(2+),an electron carrier),and platinum colloid was irradiated,continuous hydrogen production was observed with the irradiation time.The amount of hydrogen production was about 10.5mumol after 4 h of irradiation under the optimum condition.
