Abstract This study investigates thermal aging induced effects on the surface properties of model and commercial automotive catalysts for Natural Gas Vehicles, by means X‐ray photoelectron spectroscopy infrared chemisorbed CO as a probe molecule noble metals. Post‐combustion this application are essentially composed palladium containing low amounts rhodium additives to improve oxygen storage properties. The procedure involved exposing an oxidizing atmosphere air 10 vol.% H 2 O at 980 °C 4 h...
Temporal Analysis of Products (TAP) investigation on Natural Gas-fueled Vehicle (NGV) catalysts provides information related to the nature reaction steps involved over noble metals and at metal-support interface. The determination accurate kinetic parameters for methane adsorption from single pulse experiments subsequent sequential surface reactions alternative CH4/O2 is first step toward establishment relevant structure/activity relationships which can highlight importance metal/support...
This paper deals with the kinetics of reduction NO by H2 on Pd supported over reducible supports, such as LaCoO3. An extensive kinetic investigation was performed aged catalysts after exposure to successive reductive and oxidative atmospheres at a high temperature (T = 500 °C). Typically, Pd/LaCoO3 reduced in pure then under reactive conditions presence an excess O2. Both thermal treatments are accompanied significant bulk surface reconstructions characterized X-ray diffraction photoelectron...
NGV Pd-doped LaMnO3 catalysts have been studied for the CH4/O2 reaction in lean conditions. Pd incorporation during sol-gel synthesis has compared to a classical wet impregnation of perovskite support. The calcination temperature obtain structure turned out be key determine strength interaction between and LaMnO3. Both parameters extent surface reconstructions aging. impact such changes highlighted through steady-state kinetic measurements modeled according single site or dual mechanism...
