Influence of partial dealumination of BEA zeolites on physicochemical and catalytic properties of AgAlSiBEA in H2-promoted SCR of NO with ethanol

Nataliia O. Popovych, Pavlo I. Kyriienko, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

The two-step postsynthesis method allows obtaining AlSiBEA zeolites with different degree of dealumination (Si/Al = 100 and 200). Physicochemical properties (crystallinity, hydroxyl group coverage, acidic sites and nature of silver species) of AlSiBEA and AgAlSiBEA were investigated by XRD, DR UV–…

Co-Al Mixed Oxides Prepared via LDH Route Using Microwaves or Ultrasound: Application for Catalytic Toluene Total Oxidation

Eric Genty, Julien Brunet, Christophe Poupin, Sandra Casale, Sylvie Capelle, Pascale Massiani, Stéphane Siffert, Renaud Cousin

Co6Al2HT hydrotalcite-like compounds were synthesized by three different methods: co-precipitation, microwaves-assisted and ultrasound-assisted methods. The mixed oxides obtained after calcination were studied by several techniques: XRD, TEM, H2-TPR and XPS. They were also tested as catalysts in…

Synthesis and Characterization of Temperature-Responsive N-Cyanomethylacrylamide-Containing Diblock Copolymer Assemblies in Water

Nicolas Audureau, Fanny Coumes, Clémence Veith, Clément Guibert, Jean-Michel Guigner, François Stoffelbach, Jutta Rieger

We have previously demonstrated that poly(N-cyanomethylacrylamide) (PCMAm) exhibits a typical upper-critical solution temperature (UCST)-type transition, as long as the molar mass of the polymer is limited, which was made possible through the use of reversible addition-fragmentation chain transfer…

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…

TiO2-Copper on smart textiles in a prototype plug flow reactor for enhanced photocatalytic removal of contaminants in fruit storage environments

Sarra Karoui, Amine Aymen Assadi, Nabisab Mujawar Mubarak, Abdeltif Amrane

The photocatalysis technique was chosen for its non-toxicity and high efficiency in combating indoor air pollution caused by volatile organic compounds (VOCs) and microorganisms. This paper investigates and discusses the simultaneous gas-phase removal of Ethyl acetate (EA) and Escherichia coli (E.…

Chemically and Physically Pretreated Straw in Moderate Conditions: Poor Correlation between Biogas Production and Commonly Used Biomass Characterization

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

Straw is a substantial agricultural by-product for biogas production. Hydrolysis of straw is found to be a rate-limiting step during its anaerobic digestion and could be enhanced by pretreatment. In this paper, the effect of various combinations of particle size reduction, autoclaving, and low-…

Framework Stabilization of Ge-Rich Zeolites via Postsynthesis Alumination

Ff Gao, M Jaber, K Bozhilov, A Vicente, Christian Fernandez, V Valtchev

The use of organic structure directing agents in zeolite syntheses has dramatically extended the number of zeolite structure types during the past decades. However, for about 20% of all known zeolite structure types, the necessary postsynthesis elimination of organic templates by high-temperature…

Silk foams with metallic nanoparticles as scaffolds for soft tissue regeneration

Claire de Lartigue, Cristina Belda Marín, Vincent Fitzpatrick, Antonella Esposito, Sandra Casale, Jessem Landoulsi, Erwan Guénin, Christophe Egles

Tissue regeneration can be achieved by providing endogenous cells with a biomaterial scaffold that supports their adhesion and proliferation, as well as the synthesis and deposition of an extracellular matrix (ECM). In this work, silk fibroin protein foams were formed by lyophilization to generate…
