Outline of Final Research Achievements

Bioethanol, biodiesel, and biogas have gained much attention as sustainable energy alternatives to petroleum-based fuels. Bio-ethanol production from lignocelluloses is the most typical method to provide liquid fuel, since they are not directly in competition with food sources. However, ethanol concentration is usually too low to separate by distillation at a low-energy cost. Gaseous H2 is spontaneously isolated without operation to separate. Therefore, H2 production is an economical approach to biofuels. We dealt with the photocatalytic H2 production (PR) using sacrificial water-soluble materials derived from lignocelluloses, lipids, and chlorella. Lignocellulosic Italian ryegrass (2.00 g) was turned into H2 (78.7 mg) through alkali-treatment, hydrolysis, and PR processes. The PR process of glycerol (10.4 g) and methanol (11.3 g), which were by-products in biodiesel-synthesis, formed H2 (3.10 g). Dried chlorella (10 g) was turned into H2 (578 mg) by protease-hydrolysis and PR.
