Hydrogen formation from glucose was examined using a batch reactor in high temperature high pressure water at 300°C. Homogenous catalysts (H<SUB>2</SUB>SO<SUB>4</SUB> and NaOH) were not effective for H<SUB>2</SUB> formation from glucose at this condition. Heterogeneous catalysts: Ag<SUB>2</SUB>O, CuO, Cr<SUB>2</SUB>O<SUB>3</SUB>, Fe<SUB>2</SUB>O<SUB>3</SUB>, MgO, MnO<SUB>2</SUB>, MoO<SUB>3</SUB>, NiO, rutile TiO<SUB>2</SUB>, and ZnO, were applied and then it was found that MnO<SUB>2</SUB> and ZnO effectively promoted H<SUB>2</SUB> formation. In order to enhance H<SUB>2</SUB> yield, glucose in high pressure high temperature water was partially oxidized in the presence of ZnO. As a result, 25 % H<SUB>2</SUB> (glucose mole basis) was obtained. In this reaction, by-production of methane was not observed. The enhancement of H<SUB>2</SUB> yield was not observed when ZnO was located at gas phase. It suggested that a precursor of H<SUB>2</SUB> formed in the aqueous phase.
