Research Abstract

The use of photocatalysts like titanium dioxide in the hydrothermal gasification process of biomass has been studied for substantially lowering the reaction temperature. We first constructed a flow-type reaction system and examined the gasification of ethanol. Glucose and water-soluble cellulose were then used as model materials for biomass. We found that the methane evolution was enhanced by the photocatalytic action of titanium dioxide. It was also revealed that the hydrogen evolution from cellulose was promoted by loading ruthenium on titanium dioxide photocatalyst
