P839: Nanoporous materials in chemical education

Thomas Waitz (Georg-August-University Goettingen, Germany)

The meaning and versatility of nanoporous materials like silica, carbon, and metal oxides in chemical education is presented by some basic and easy to implement model experiments. These include modern syntheses strategies like ‘soft-matter templating’ and ‘nanocasting’ which can easily be realized in school chemistry. Additionally, fields of application like chromatography, separation, gas storage, and gas sensing will be presented. The latter example will be elucidated in some detail, since educational aspects of semiconducting gas sensors are particularly manifold. Resistive gas sensors play a major role in numerous areas of everyday life, including environmental analysis, monitoring of air quality, or as ‘electronic noses’, e.g. for controlling cooking and roasting processes in modern baking ovens.
