SOLAR HYDROGEN PRODUCTION FROM CELLULOSE WITH ARTIFICIAL PHOTOSYNTHESIS SYSTEM

摘要

In the environmental science and the energy source development, hydrogen gas production from renewable resources of timber waste, including cellulose, lignin, etc. is important. We have previously reported the enzymatic photoinduced hydrogen production from sucrose or maltose as the renewable bio-resources using the light-harvesting function of Mg Chl-a. And the photoinduced hydrogen production from water-soluble methylcellulose using the light-harvesting function of Mg Chl-a, also has been accomplished. However, soluble cellulose derivative, methylcellulose is used as a renewable resource in this hydrogen production system. Thus, photoinduced hydrogen production from renewable resources of timber waste, including insoluble cellulose is not accomplished yet. In this paper solar hydrogen production system by coupling the waste paper including cellulose with cellulase and GDH, and hydrogen production with platinum colloid via the photoreduction of MV~(2+) using the visible light-harvesting function of Mg Chl-a is developed.
