abstract={We present a gas sensor using nanoporous titanium dioxide which is fabricated by anodic oxidation of a titanium foil. The process is easy to handle, can be carried out at low cost and the sensor response to reducing gases can be measured using a cheap digital multimeter. In contrast to the most gas sensors, no commercially available sensor substrate is required. The band model for semiconductors and a model of ionosorption provides an explanation for the working principle of the gas sensor on particle level. Several experimental approaches for upper-secondary chemistry class are presented.},
