Synthesis of clay-like lamellar compounds

Clays and clay minerals are widely distributed worldwide, however, various structural compositions as well as the presence of different phases (such as quartz, calcium carbonate) or, in some cases, traces of elements such as arsenic (that may cause problems during the final application) may limit their uses depending on the targeted application. One way to circumvent these impediments is to synthesize clays. The hydrothermal synthesis methods make it possible to obtain lamellar compounds of well-defined chemical compositions via careful control of the parameters governing the formation of the lamellar structures. Current research is focused on the development of more environmentally-friendly processes, that use less water and can be carried out at lower temperatures than those usually employed (220°C). Special attention is paid to the characterization of the compounds by a multi-technique approach. The obtained lamellar phases can be used as model compounds (for example for the study of the interactions with radionuclides or as fillers for polymers and photopolymers).
Another original and innovative approach, still not extensively investigated for the synthesis of lamellar compounds, is the sol-gel route. Here, an organoalkoxysilane RSi (OR’)3, where R stands for an organic moiety and R’ is a methoxy or ethoxy group, is used as a silicon source. The advantages of this process are numerous : the materials are obtained at ambient temperature, the synthesis requires short times, and the lamellar structure is directly functionalized via the organic group bonded by covalent bond to the silicon of the tetrahedral sheet. Recent research has helped to obtain new insight into the formation mechanism of such organic-inorganic hybrids having a talc-like structure. Studies are underway to render the process even more environmentally-friendly and to obtain multifunctional compounds.

Formulation of composite materials for separation, controlled release of active molecules and adsorption of pollutants in gas and liquid phase

The cationic exchange properties of clays make them attractive as host networks for trapping pollutants, releasing certain active molecules in a controlled way, or modifying the photochemical properties of dyes. As part of the CNRS Fapesp 2016 / 50317-9 bilateral contract, the nature of the interactions between the mineral framework and active molecules will be determined. The therapeutic potential of these compounds and their use as a diagnostic device for controlled and targeted release of biologically active molecules will also be investigated. Another aspect of the research concerns the in situ confinement of compounds in hybrid organic-inorganic structures and the impact of such a confinement on the properties of the synthesized composites.

Material and energy recovery of biobased products : production of chars
M. Jeguirim*, L Limousy, S. Bennici
*Contact : mejdi.jeguirim@uha.fr
The development of renewable energies has become a major challenge to overcome fossil fuels depletion and increased greenhouse gas emissions. Among the various high-potential strategies, the thermochemical conversion of biomass resources could be an alternative technique for green energy production and carbon sequestration. Pyrolysis process has the notable advantage of producing liquid and gaseous fractions that can be turned into biofuels, and a solid fraction (called char) that can be used in various applications. Thus, the char can be directly used for soil amendment (called biochar), gasified under water vapor and/or CO2 for producing syngas or converted into adsorbent for the removal of pollutants in gaseous and aqueous phases.

Recently, a strategy for reusing the aqueous effluents derived from the food processing industry has been established. These food processing effluents, rich in organic compounds and minerals, can be impregnated on biosourced materials. The mixture obtained is then dried to recover the water and the residue is pyrolyzed for producing bio-oils and biochar. The derived biochar is rich in nutrients such as potassium (K), phosphorus (P) and nitrogen (N) and could be used as biofertilizer for soil amendment.

Thermochemical heat storage
S. Bennici*, P. Dutournié
*Contact : simona.bennici@uha.fr
An efficient way to save energy is to replace conventional energy sources with clean and renewable ones, and to recover the fatal heat issued from various industrial plants. This strategy also helps to reduce the use of fossil fuels, and consequently, the associated pollution. On the other hand, the intermittent nature of renewable energy sources calls for the identification of technologies able to balance the temporal incongruity between the energy supply and demand. These technologies must be based on systems capable of storing excess energy (when the resource is abundant) to be reused when needed.
The research of new storage systems based on the use of innovative storage materials is crucial. Composites based on hydrated salts have been developed to improve the energy density and the power of thermochemical heat storage systems. The overall heat storage process must be taken into account, starting from the preparation and characterization of the composite material, until its application in semi-pilot and pilot systems. Moreover, an accurate study of the heat and mass transfers must be carried out for up-scaling purposes and for integration into existing plants (in the case of fatal heat recovery).

Nanofiltration and ultrafiltration
P. Dutournié*, L. Limousy
*Contact : patrick.dutournie@uha.fr
The most recent research has been focused on nanofiltration and ultrafiltration membranes (low molecular weight cut-off). These investigations are based on experimental and numerical studies of the involved mass transfers, and on the identification of the solute / solvent / surface interactions with the pores and at the surface of porous materials. Even if the scientific community agrees to model the transfer of ionic solutes through the pores of a membrane as the sum of the three contributions (steric, electrical and dielectric effects), these ones are still only partially known and generally difficult to evaluate. In this context, an approach combining the experimental (synthesis, realization of inorganic membranes and filtration tests), the characterization (textural and structural properties, interaction energies …) and the development of theoretical and numerical tools (for the simulation and estimation of the membrane properties by inverse techniques, …) has been developed. These activities have resulted in the realization of new objects (with specific hydraulic properties and selectivity), the establishment of an original 2D simulation tool (integrating the boundary layer), and finally, an evaluation of the interactions between the solvent, the surface and the solute.
