PURPOSE:To increase the formation efficiency of gaseous hydrogen by depositing various compds. of transition metals, which are used as an electrode catalyst, on a carrier to make a photocatalyst in the photocatalytic manufacture of hydrogen from an aq. soln. of methanol. CONSTITUTION:After packing a photocatalyst into a transparent reaction tube, an aq. soln. of methanol having 10-60wt% concn. is added therein. Gaseous H2 is generated from the aq. soln. of methanol by irradiating the light. As the photocatalyst to be used at this time, TiO2 is used as a carrier, and >=1 kind selected from the boride, nitride, phosphide, and carbide of transition metals such as Ti, Zr, Nb, Ta, Cr, and Mo, especially WC which are used as an electrode catalyst are deposited on the surface of the carrier. In this way, gaseous hydrogen can be manufactured with excellent generation efficiency.
