Abstract

This paper describes and analyzes the appearance, phase, and photocurrent of titanium film surfaces after exposure to water vapor at 100–1000 °C. The experimental results show that water vapor at higher than 300 °C can cause measurable oxidation of the titanium surface, and the oxidation product is changed into rutile from anatase in a gradual phase transformation with temperature. In the reaction, the product produced at 500–900 °C is a mixed phase of rutile and anatase. The titanium film surface appearance can change regularly with temperature, and an acicular rutile oxidation product can be produced on the surface at 800 °C. The photocurrent density on titanium surface increases with reaction temperature, and comes to a maximum value at 800 °C. However, with further increase in reaction temperature, the density decreases.
