Investigation of different catalytically active and passive materials for realising a hydrogen peroxide gas sensor

In this work, different materials have been investigated for the realisation of a calorimetric sensor for the detection of hydrogen peroxide. Therefore, a test equipment for the realisation of different H2O2 concentrations as well as H2O concentrations at different temperatures has been built. As catalytically active materials copper, and diverse manganese oxides have been characterised. As passive materials nickel as well as PFA (Perfluoralkoxylalkan) have been applied for constructing a reference sensor. The materials with the best performance have been chosen for the realisation of an H2O2 sensor in a TO (transistor outline) housing. The sensor has been characterised towards the H2O2 sensitivity and the disturbing factors H2O concentration and temperature. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
