Covalent immobilization of glucose oxidase on mesocellular silica foams: Characterization and stability towards temperature and organic solvents

Noemie Balistreri, Dorian Gaboriau, Claude Jolivalt, Franck Launay

Glucose oxidase (GOx) immobilization onto mesoporous SBA-15 silica and two mesocellular foams (MCF) characterized by similar surface area and pore volumes but different pore/cell dimensions was examined. The covalent grafting of the enzyme through amide bonds was evidenced by controlling pH…

Photoelectrochemical properties of nanocrystalline ZnS discrete versus continuous coating of ZnO nanorods prepared by electrodeposition

A. Brayek, S. Chaguetmi, M. Ghoul, I. Ben Assaker, A. Souissi, L. Mouton, P. Beaunier, S. Nowak, F. Mammeri, R. Chtourou, S. Ammar

We developed nanostructured photoanodes for photoelectrochemical (PEC) water splitting and hydrogen generation. They are based on ZnO nanorods electrodeposited on conductive ITO glass on which ZnO@ZnS heterojunctions were formed using two different approaches. In the first case, the ZnO nanorods…

Combined fungal and chemical pretreatment of lignocellulosic biomass for biogas production: Effect of pretreatment order and fungal strains

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

The recalcitrance of lignocellulosic poses a challenge for conversion to biogas and therefore, pretreatment is an essential step in addressing this. Combining fungal pretreatment with a biomimetic system, a mild Fenton reaction, was studied to improve the methane production from straw. The…

Characterization of as-synthesized MOx-MCM-41 (M=Mo, W) mesophases using Raman spectrometry and 29Si MAS NMR.

J.-V. Piquemal, E. Briot, G. Chottard, P. Tougne, J.-M. Manoli, J.-M. Brégeault

MCM-41 mesostructured silicas containing molybdenum and tungsten have been prepared in an acidic medium at room temperature. Two procedures were considered: the so-called oxo–peroxo route with low-nuclearity peroxo metal precursors (route A) and the oxo–polyoxo pathway, involving or generating…

Maghemite nanoparticles and maghemite/silica nanocomposite microspheres as magnetic Fenton catalysts for the removal of water pollutants

Nassira Ferroudj, Jimmy Nzimoto, Anne Davidson, Delphine Talbot, Emmanuel Briot, Vincent Dupuis, Agnès Bée, Mohamed Salah Medjram, Sébastien Abramson

Maghemite nanoparticles (-Fe 2 O 3 NP) and maghemite/silica nanocomposite microspheres (-Fe 2 O 3 /SiO 2 MS) have been evaluated as magnetic heterogeneous Fenton catalysts. The catalysts were fully characterized by electronic microscopies, magnetometry, XRD, UV–vis–NIR spectroscopy, and sorption…

Cation redistribution upon dehydration of Na 58 Y faujasite zeolite: a joint neutron diffraction and molecular simulation study

Wilfried Louisfrema, Benjamin Rotenberg, Florence Porcher, Jean-Louis Paillaud, Pascale Massiani, Anne Boutin

Using neutron scattering and Monte Carlo simulation, we investigate the distribution of cations in Na58Y faujasite upon (de)hydration. We introduce a new method for the assignment of cations to specific sites in molecular simulations from their local environment. This allows us to bypass the need…
