Patent number: 8871877Abstract: The present invention relates to materials and particularly “organometallic-organic-inorganic hybrid materials” that can be used as heterogeneous catalysts for selective catalytic reactions. More precisely this invention relates to organic-inorganic hybrid nanostructured materials comprising a regularly distributed stabilized carbene that binds strongly to a metal so as to form a stable organometallic-organic-inorganic hybrid material having high catalytic performances.Type: GrantFiled: January 23, 2009Date of Patent: October 28, 2014Assignee: Universite Claude Bernard Lyon 1 (UCBL)Inventors: Chloe Thieuleux, Christophe Coperet, Laurent Veyre, Robert Corriu, Catherine Reye, Ahmad Mehdi, Jean-Marie Basset, Tarun Maishal, Malika Boualleg, Iyad Karame, Jean-Michel Camus, Johan Alauzun

Patent number: 7517512Abstract: The invention concerns a method for preparing organic-inorganic hybrid materials with controlled porosity and functionality comprising hydrolysis and condensation polymerization of a compound of formula (I): Z-R1—Si(OR)(OR?)(OR?), with an alkaline or alkaline-earth silicate in a mol ratio of (I)/(silicate)=1:9, in the presence of a non-ionic surfactant, to form a mesoporous silica represented by Z-R1—SiO1.5 9 SiO2, whereon is then anchored an organic compound, represented by (?)N—H, comprising a —NH— group capable of reacting with Z, to form a functionalized mesoporous silica represented by (?)N—R—SiO1.5 9 SiO2, which is optionally complexed with a metallic cation to form an organometallic complex. The invention also concerns the use of these materials to separate gases.Type: GrantFiled: March 6, 2008Date of Patent: April 14, 2009Assignee: Centre National de la Recherche-ScientifiqueInventors: Robert Corriu, Ahmad Mehdi, Catherine Reye, Henry Ledon, Roger Guilard, Stéphane Brandes, Chloé Thieuleux

Patent number: 6524372Abstract: A novel compound which can be used in the field of separation and purification of gases is disclosed. The compound can be incorporated into a silica gel incorporating polyazacycloalkane structural units for separating a predetermined gas from a mixture of gases. The mixture of gases is brought into contact with a metallated hybrid gel under conditions which make possible the absorption of the gas to be separated, followed by a phase of desorption of the attached gas, and the recovery of the gas.Type: GrantFiled: July 25, 2000Date of Patent: February 25, 2003Assignee: L′Air Liquide, Societe Anonyme a Directoire et Conseil de Surveillance pour l′Etude et l′Exploitation des Procedes Georges ClaudeInventors: Robert Corriu, Catherine Reye, Ahmad Mehdi, Gérard Dubois, Claude Chuit, Franck Denat, Bruno Roux-Fouillet, Roger Guilard, Gilles Lagrange, Stéphane Brandes
