(Closed) NanoCatRed – Novel metallic NANOparticles on NANOstructured supports for oxyanion CATalytic REDuction in water - UT Austin Portugal (original) (raw)

Summary

Several health risks have been associated with the occurrence of inorganic contaminants in water. Neither existing conventional nor advanced water treatment technologies have ticked in both efficiency and environmental criteria. NanoCatRed proposes the development of nanostructured catalysts that can achieve a step-change in the performance of catalysts for hydrogenation of inorganic contaminants in water.

The NanoCatRed project is designed to take advantage of two different concepts in heterogeneous hydrogenation catalysts to achieve a step-change in the efficiency in water purification applications: new methodologies for the fabrication of more active/less costly metallic nanoparticles, and new methodologies for the fabrication of nanostructured supports that can enhance the activity/selective/stability of the active metal phase.

Catalytic hydrogenation is a promising technology for two main reasons: 1) it acts on the removal of oxygen-containing anionic contaminants (oxyanions) such as bromate, nitrate, and perchlorate, which can be harmful to health, from the water; 2) it prevents the generation of secondary waste streams.

The project will focus on the development of nanostructured catalysts, specifically by screening their performance in the reduction of bromate, nitrate, and perchlorate to non-harmful products. The best performing catalysts will be selected for testing in a lab-scale pilot unit, using real waters sourced within the NanoCatRed’s network and the leader beneficiary’s customer portfolio. The pilot testing unit will evaluate the catalysts’ capability to achieve contamination levels below those in the relevant legislation or recommended by the authorities when used in practical application conditions.

Expected Outcomes

• Innovative technology based on nanostructures catalysts for removal of oxygen-containing anionic contaminants (oxyanions) from the water without the generation of concentrated secondary waste streams and aiming at the surface and ground water treatment sector;
• Scientific papers for publication in specialized peer-reviewed and open-access journals, some of which will be co-authored by the company and the research units;
• Promotional materials to raise awareness of the project and accelerate market uptake of the developed technology.
