Abstract
A porous CaZrO3/MgO composite with similar to1% nanodispersed platinum was
synthesized in air using several in situ reactions, including the pyrolysis
of PtO2. The composite had a uniformly open, three-dimensional pore struct
ure (porosity of 56%), with a narrow pore-size distribution. Catalytic NO d
ecomposition to N-2 and O-2 and NO reduction by C(2)H4 were investigated up
to 900 degreesC. In the absence of oxygen, the NO conversion rate reached
similar to 52% for the direct decomposition and similar to 100% for the red
uction by C2H4. The results suggested the possibility of the porous composi
te as a multifunctional filter for simultaneous filtering of hot gas and re
moval of NOx.
