Supramolecular interaction of non-racemic benzimidazolium based ion pairs with chiral substrates (2018)
Journal Article
Mumtaz, S., Cano, I., Mumtaz, N., Abbas, A., Dupont, J., & Gondal, H. Y. (2018). Supramolecular interaction of non-racemic benzimidazolium based ion pairs with chiral substrates. Physical Chemistry Chemical Physics, 20(32), 20821-20826. doi:10.1039/C8CP03881C

A series of novel benzimidazolium-based non-racemic ionic liquids (ILs) was synthesized from low–cost chiral terpenoid alcohols and fully characterized by the use of a wide variety of techniques, such as DSC, ESI-MS, ATR FT-IR, polarimetry as well as... Read More

Tuneable ionic control of polymeric films for inkjet based 3D printing (2018)
Journal Article
Karjalainen, E., Wales, D. J., Gunasekera, D. H., Dupont, J., Licence, P., Wildman, R. D., & Sans, V. (in press). Tuneable ionic control of polymeric films for inkjet based 3D printing. ACS Sustainable Chemistry and Engineering, doi:10.1021/acssuschemeng.7b04279. ISSN 2168-0485

Inkjet printing is a powerful additive manufacturing (AM) technique to generate advanced and complex geometries. However, requirements of low viscosity and surface tension are limiting the range of functional inks available, thus hindering the develo... Read More

Selective CO2 hydrogenation to formic acid with multifunctional ionic liquids (2018)
Journal Article
Weilhard, A., Qadir, M. I., Sans, V., & Dupont, J. (in press). Selective CO2 hydrogenation to formic acid with multifunctional ionic liquids. ACS Catalysis, 8, doi:10.1021/acscatal.7b03931. ISSN 2155-5435

The development of simple, cost-effective and sustainable methods to transform CO2 into feedstock chemicals is essential to reduce the dependence on fossil fuels of the chemical industry. Here, we report the selective and efficient catalytic hydrogen... Read More

Selective carbon dioxide hydrogenation driven by ferromagnetic RuFe nanoparticles in ionic liquids (2018)
Journal Article
Qadir, M. I., Weilhard, A., Fernandes, J. A., de Pedro, I., Vieira, B. J. C., Waerenborgh, J. C., & Dupont, J. (2018). Selective carbon dioxide hydrogenation driven by ferromagnetic RuFe nanoparticles in ionic liquids. ACS Catalysis, 8(2), 1621-1627. doi:10.1021/acscatal.7b03804

CO2 is selectively hydrogenated to HCO2H or hydrocarbons (HCs) by RuFe nanoparticles (NPs) in ionic liquids (ILs) under mild reaction conditions. The generation of HCO2H occurs in ILs containing basic anions, whereas heavy HCs (up to C21 at 150 °C)... Read More

Revealing Hydrogenation Reaction Pathways on Naked Gold Nanoparticles (2017)
Journal Article
Luza, L., Rambor, C. P., Gual, A., Alves Fernandes, J., Eberhardt, D., & Dupont, J. (2017). Revealing Hydrogenation Reaction Pathways on Naked Gold Nanoparticles. ACS Catalysis, 7(4), 2791-2799. doi:10.1021/acscatal.7b00391

Gold nanoparticles (AuNPs) display distinct characteristics as hydrogenation catalysts, with higher selectivity and lower catalytic activity than group 8−10 metals. The ability of AuNPs to chemisorb/activate simple molecules is limited by the low coo... Read More

Challenging thermodynamics: hydrogenation of benzene to 1,3- cyclohexadiene by Ru@Pt nanoparticles (2016)
Journal Article
Weilhard, A., Abarca, G. A., Viscardi, J., Prechtl, M. H., Scholten, J. D., Bernandi, F., …Dupont, J. (in press). Challenging thermodynamics: hydrogenation of benzene to 1,3- cyclohexadiene by Ru@Pt nanoparticles. ChemCatChem, 9(1), doi:10.1002/cctc.201601196. ISSN 1867-3880

Since the earliest reports on catalytic benzene hydrogenation, 1,3-cyclohexadiene and cyclohexene have been proposed as key intermediates. However, the former has never been obtained with remarkable selectivity. Herein we report the first partial hyd... Read More
