Mechanistic Investigations of C–H Activations on Silica-Supported Co(ii) Sites in Catalytic Propane Dehydrogenation

Autor: Deven P. Estes

Publikováno v: CHIMIA, Vol 71, Iss 4 (2017)

Catalytic reactions involving C–H bond activations are central to the chemical industry. One such example, alkane dehydrogenation, has recently become very important due to shortfalls in propene production and a large supply of cheap propane. Howev

Vers une catalyse coopérative : conception de nouveaux édifices hétérobimétalliques supportés sur silice

Autor: Lassalle, Sébastien

Organometallic chemistry has been studied mainly through the prism of monometallic molecular species. We believe that the combination of two metals of different natures, interacting through a metal-metal bond, and supported on a silica, opens up new

Tailored Isolated Copper (II) Sites on Oxide Supports for the Selective Oxidation of Methane to Methanol

Autor: Meyet, Jordan

The direct functionalization of methane, a major constituent of natural gas, into value-added chemicals remains one of the key challenges to be tackled for more responsible and sustainable use of fossil fuels and to avoid massive emissions of carbon

Exploiting Confinement Effects to Tune Selectivity in Cyclooctane Metathesis

Autor: Anissa Bendjeriou-Sedjerari, Zhen Cao, Manoja K. Samantaray, Luigi Cavallo, Eva Pump, Jean-Marie Basset

Publikováno v: ACS Catalysis. 7:6581-6586

The mechanism of cyclooctane metathesis using confinement effect strategies in mesoporous silica nanoparticles (MSNs) is discussed by catalytic experiments and density functional theory (DFT) calculations. WMe6 was immobilized inside the pores of a s

Selective Hydrogenation of CO2 to CH3OH on Supported Cu Nanoparticles Promoted by Isolated TiIV Surface Sites on SiO2

Autor: Noh, Gina, Lam, Erwin, Alfke, Jan L., Larmier, Kim, Searles, Keith, Wolf, Patrick, Copéret, Christophe

Publikováno v: ChemSusChem, 12 (5)

Small and narrowly distributed Cu nanoparticles, supported on SiO2 decorated with isolated TiIV sites, prepared via surface organometallic chemistry, show significantly improved CO2 hydrogenation activity and CH3OH selectivity compared to the corresp

Development and Understanding of Well-Defined Ni-Based Ethene Oligomerization and Homologation Catalysts

Autor: Moroz, Ilia B.

Nickel oxide supported on various oxide-based materials are known for decades to be efficient heterogeneous catalysts for oligomerization of ethene – a key industrial process for production of more valuable linear alpha-olefins. Recently, they have
