Vanadium incorporation from aqueous NH4VO3 solution into siliceous Beta zeolite determined by NMR with formation of V-single site zeolite catalysts for application in SCR of NO

Rafal Baran, Yannick Millot, Frederic Averseng, Stanislaw Dzwigaj

The speciation of vanadium in initial aqueous NH4VO3 solutions as a function of pH and concentration, in supernatant and in wet solids were investigated by 51V static and MAS NMR. Two series of VSiBeta zeolite catalysts were prepared by a two-step postsynthesis procedure at pH = 2.5 and 6. 51V…

Influence de l'incorporation du vanadium dans l'hydroxyapatite sur la réaction d'oxydation déshydrogénante du propane, Influence of the incorporation of vanadium in hydroxyapatite on the oxidative dehydrogenation of propane reaction

Sarah Petit

Dans l'objectif de combler le gap entre l'offre et la demande en propène, la réaction d'oxydation déshydrogénante du propane (ODHP) est une solution alternative à la réaction de déshydrogénation directe. Les hydroxyapatites (HAp) modifiées au vanadium sont des matériaux bi-…, In order to fill the gap between propene supply and demand, the oxidative dehydrogenation of propane (ODHP) is an alternative solution to the direct dehydrogenation process. Vanadium-modified hydroxyapatites (HAp) are bifunctional catalysts combining acid-base and redox properties which were shown…

Synthesis of supported ZSM-5 nanoparticles

Olfa Ben Moussa, Ilef Borghol, David Hu, Sandra Casale, Yannick Millot, Celine Sayag, Juliette Blanchard, Olivier Durupthy

The influence of the support on the nucleation of ZSM-5 nanoparticles has been studied for three supports: γ-alumina, zirconia and carbon nanotubes (CNT). While zeolite nucleation was suppressed in presence of alumina and strongly delayed in presence of zirconia, it occurred without delay in…
