Abstract

Photocatalytic hydrogen production was first detected in a high vacuum condition for platinum-loaded nanocrystalline anatase-titanium dioxide (TiO ₂) thin films, using a newly developed monitoring system with a quadrupole mass spectrometer. In the presence of methanol of 10^-6 Torr, partial pressures of hydrogen (H₂) and formaldehyde (HCHO), generated due to the decomposition of methanol, were observed clearly to change simultaneously with the UV irradiation onto the TiO₂ films. Photolysis of gas-phase water was also detected, thus revealing that this new method is capable to evaluate sensitively such the photocatalytic activities in high vacuum at a real-time scale.
