Investigation Of Differentcatalytically Active And Passive Materialsrnfor Realising A Hydrogen Peroxide Gas Sensor

摘要

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 H_2O_2 concentrations as well as H_2O concentrations at different temperatures has been built. As catalytically active materials copper, and diverse manganese oxides have been characterised.rnAs passive materials nickel as well as PFA (Perfluoralkoxy-lalkan) have been applied for constructing a reference sensor. The materials with the best performance have been chosen for the realisation of an H_2O_2 sensor in a TO (transistor outline) housing. The sensor has been characterised towards the H_2O_2 sensitivity and the disturbing factors H_2O concentration and temperature.
