PdOx/Pd at Work in a Model Three-Way Catalyst for Methane Abatement Monitored by Operando XANES
The oxidation state of palladium in a model Pd/ ACZ three-way catalyst was monitored by synchronous XANES and mass spectrometry during two consecutive heating (to 850 C) and cooling (to 100 C) cycles under stoichiometric conditions simulating exhaust after treatment of a natural gas engine. During heating in the first cycle, PdO reduction occurred around 500 C and the initial fully oxidized sta...
متن کاملIn 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 significantly affected by aging in the reduced case (λ = 0.98). The catalyst aging state can theref...
متن کاملIsotopic Studies of Methane Oxidation Pathways on PdO Catalysts
Mechanistic details of CH4 oxidation were examined on PdO/ ZrO2 catalysts using isotopic tracer methods and measurements of kinetic isotope effects. Normal kinetic isotope effects were observed using CH4/O2 and CD4/O2 reactant mixtures. The (kH/kD) ratio was between 2.6 and 2.5, and it decreased slightly as the reaction temperature increased from 527 to 586 K. These kinetic isotope effects refl...

متن کاملComparison of Aged and fresh Automotive Three-Way Catalyst in Driving Cycle
Recently, environmental concern and demand for a catalyst’s high performance have increased and many research activities focused on the operation of a three-way catalyst (TWC) at the end of its lifetime. Catalyst aging is the loss of catalytic activity over time that has crucial importance in emission of three-way catalyst. The aim of this paper is, investigating experimentally the performanc...
