AbstractMicro-kinetic modeling of Pt-catalyzed hydrogen oxidation in a monolithic reactor was carried out for various feed temperatures. The monolith behavior was described by a simplified steady-state model that avoids surface species enthalpy evaluation and does not have temperatures as unknowns. A simplified pseudoarch length method was used to obtain the multiple solution branches for this typical exothermic reaction system. Based on parametric sensitivity and surface species distribution analyses of the micro-kinetic modeling results, macro-kinetic models that involve only gas concentrations were derived and were used to explain the composition effects on ignition temperature.

Micro-thermoelectric hydrogen sensor (micro-THS) with the combination of the thermoelectric effect of Si0.8Ge0.2 thin film and the Pt-catalyzed exothermic reaction of hydrogen oxidation was prepared by microfabrication process. In the viewpoint of high sensitivity of micro-THS, the thermoelectric properties of the Si0.8Ge0.2 thin film could be improved by optimizing carrier concentration using helicon sputtering with an advantage of easy doping control, and sensitivity of the device with this thin film was investigated. As the result, the boron-doped Si0.8Ge0.2 thin film is considered to be the better choice ensuring the reliable monitoring of hydrogen concentration down to ppm level.
