An in situ DRIFT and mass spectrometric study of catalytic partial oxi
dation of methane with Ir/alpha-Al2O3 has enlightened relationships be
tween the formation of surface metal carbonyl clusters and residence t
ime and temperature conditions. Some cluster species produced during c
atalytic partial oxidation were also originated during CO2 hydrogenati
on and CO2 reforming experiments described in previous literature. An
EXAFS analysis of the catalyst precursor, prepared through a solid-liq
uid reaction between Ir-4(CO)(12) clusters and the reactive surface si
tes of alpha-Al2O3, is also included to discuss clusters structure pro
duced at the surfaces.
