Abstract:A heterogeneous catalyst, composed of an open-cell glass foam support impregnated with zerovalent ruthenium nanoparticles (loading around 0.1 wt.%), was used to remove toluene in air by catalytic ozonation. Experiments with lab-designed 2-6 cm length and 1.6 cm diameter catalysts were performed. A model based on the Langmuir-Hinshelwood mechanism, coupled with mass transfer limitations and including competitive effects between toluene and ozone, was designed. It accurately fits experimental data gathered at va… Show more
“…To vary the palladium source, a completely different kind of OCF was also used. It was a glass OCF, similar to that described in Cabrol et al 19 for the deposit of Ru nanoparticles, here containing Pd nanoparticles. A home-made glass OCF cylinder was impregnated 5 successive times by a colloidal suspension of Pd(0) synthesized by the chemical reduction of an aqueous solution of tetrachloropalladate( ii ) hydrate salt with sodium borohydride in the presence of N , N -dimethyl- N -cetyl- N -(2-hydroxyethyl)ammonium chloride (HEA16Cl) salt as protective agent.…”
For the Suzuki-Miyaura C-C coupling, it is well accepted that the active catalytic species in the liquid phase are leached from the solid palladium precursor. This was demonstrated for shaped...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
