Abstract

Photocatalytic hydrogen production with gas-phase reactions in high vacuum was examined for nanocrystalline anatase-type titanium dioxide (TiO₂) thin films. The hydrogen generation process on platinized TiC₂ specimens was investigated using a quadrupole mass spectrometer at a real-time scale under various partial pressures of gaseous methanol and water. As a result, hydrogen generation was successfully detected under ultraviolet (UV) ray illumination even in high vacuum (-10^-7 Torr). And the amount of produced H₂ largely depends on the temperature of TiO₂ samples, probably due to different surface states of TiO₂. This study suggests the possibility of new high-speed H₂ production system with gas-phase photocatalytic reactions.
