In operando Detection of Three-Way Catalyst Aging by a Microwave-Based Method: Initial Studies

Initial studies on aging detection of three way catalysts with a microwave cavity perturbation method were conducted. Two physico-chemical effects correlate with the aging state. At high temperatures, the resonance frequencies for oxidized catalysts (λ = 1.02) are not influenced by aging, but are...
