Abstract
Disclosed is a method to make and an apparatus for monitoring the exhaust gas conversion efficiency of a catalytic converter. The catalytic calorimetric sensor disclosed includes a sol-gel processed washcoat and sol-processed catalytically active metal particles. Sol-gel processing creates a washcoat with high surface area and controlled porosity which increases the sensitivity, durability, and reproducibility of the resultant sensor.
Claims11
A catalytic calorimetric sensor, comprising:
- a substrate;
- a temperature measuring layer disposed on said substrate;
- and
- a sol-gel processed catalytic layer disposed on said temperature measuring layer to provide a thin catalytic layer having increased sensitivity.
