Deposition of Pt-Catalyst in a micro-channel of a Silicon reactor/ Application to gas micro-TAS working at high temperature

Abstract

The study concerns a catalytic micro-reactor with the goal of gas detection. The objectives are: (i) to develop a silicon "micro-reactor" with its heater, (ii) to deposit catalysts in the micro-channels of the device, and (iii) to study catalytic conversions of this system. The main results are related to the temperature control and to the deposition of the catalyst in the micro-channel by wash-coat for alumina and impregnation for platinum. This micro-reactor is evaluated for the conversion of CO into CO2 for gas sensor applications. The current experiments demonstrate the possibility to use such micro-component to improve the selectivity of CH4 detection devices with mixtures of CH4 and CO.
