AXIS B Catalysis and Materials for Energy and Environment

This theme aims at developing new ways for 1) the production of value-added chemicals from raw materials through catalytic processes, 2) the conversion and storage of energy through physical-chemical processes and 3) the detection, capture and degradation of pollutants.

Innovative Catalytic Methodologies for Biomass conversion and CO₂ activation.

Reactions and processes implementing renewable reactants (CO₂ and biomass), displaying improved atom-economy and/or functioning under mild conditions are targeted to ultimately provide the bulk and fine chemicals supplied by the chemical industry.

Along these lines,transformations and shortcut catalyzed synthetic routes to value-added chemicals under environmentally friendly conditions, i.e.using clean oxidants or reductants, enzymatic or electrochemical methods, and developing complementary methodologies such as electro- and photocatalysis, microwave, flow chemistry, high-throughput screening, supported homogeneous catalysis, non-conventional media, are looked for.

Energy Conversion and Storage.

The three challenges to tackle are:

1- Development of materials and devices forH₂ production, storage and use, based on cost-effective molecular systems or materials as well as catalysts for Proton Exchange Membranes (PEM) or Solid Oxide (SO).

2- Development of molecular systems, materials or devices for the direct conversion of solar energy into chemical energy by photoelectrochemical processes.

3- Development of highly efficient electrochemical storage energy materials for renewable energy production and mobility applications implementing various solutions. High energy and long lifetime electrodes for advanced Li-ion batteries (the most mature), high-energy and stable anodes for Mg-ion batteries (more prospective), and advanced nanostructured materials for supercapacitors (a requirement in the transportation sector) are targeted.

Depollution and remediation.

Depollution processes (including pollutant storage, detection and degradation) based on materials structured at different levels are targeted. Innovative catalytic porous materials exhibiting stability, renewability and eco-compatibility must be developed by integrating chemo-, photo- or electro-responsive molecules, supramolecular assemblies or nanoparticles within adapted matrices (surfaces, polymers or functional materials).
