Iron oxide-mediated semiconductor photocatalysis vs. heterogeneous photo-Fenton treatment of viruses in wastewater. Impact of the oxide particle size
César Pulgarin, Michaël Bensimon, Anna Carratala Ripolles, Masoud Talebi Amiri, Sami Rtimi, Stefanos Giannakis, Siting Liu
The photo-Fenton process is recognized as a promising technique towards microorganism disinfection in wastewater, but its efficiency is hampered at near-neutral pH operating values. In this work, we overcome these obstacles by using the heterogeneous photo ...
Elsevier2017Chelating agents as coating molecules for iron oxide nanoparticles
Heinrich Hofmann, Josefina Adriana Maria Bastiaansen, Marijana Mionic Ebersold, Débora Bonvin
Due to their high chemical affinity towards metal ions, chelating agents (CAs) have been used for decades for water purification, but also for protection against metal intoxication and in nanomedicine as linking molecules at the surface of nanoparticles. H ...
RSC Publishing2017Hydrothermal growth of iron oxide NPs with a uniform size distribution for magnetically induced hyperthermia: Structural, colloidal and magnetic properties
Heinrich Hofmann, Kurt Schenk, Olivier Jordan
Magnetic iron oxide nanoparticles with a narrow size distribution were synthesized by hydrothermally treating suspensions of iron oxide nanoparticles. Ricinoleic-acid-coated magnetic nanoparticles were co precipitated at room temperature from an aqueous so ...
Elsevier2017Optimisation of aqueous synthesis of iron oxide nanoparticles for biomedical applications
Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin
Iron oxide nanoparticles (IONPs) were prepared via aqueous synthesis which combines alkaline co-precipitation (CP) of ferric and ferrous precursors with mild hydrothermal (HT) treatment without cupping agents (CA). In this novel synthesis route, CP + HT, w ...
Springer Verlag2016An operando emission spectroscopy study of Pt/Al2O3 and Pt/CeO2/Al2O3
In situ time-resolved spectroscopic examination of catalysts based on well dispersed nanoparticles on metal oxides under transient conditions significantly facilitates the elucidation of reaction mechanisms. In this contribution, we demonstrate the level o ...

Christian Ludwig, Andrea Testino, Mohamed Tarik, Frank Pilger
The facile one-pot synthesis of CeO2-based catalysts has been developed to prepare a relatively large amount of nanopowders with relevant catalytic activity towards CO oxidation. The method consists of a two-steps process carried out in ethylene glycol: in ...
Amer Scientific Publishers2015Polymer Adsorption on Iron Oxide Nanoparticles for One-Step Amino-Functionalized Silica Encapsulation
Heinrich Hofmann, Lionel André Maurizi
This paper presents an original method to obtain, in one step, core/shell nanoparticles grafted covalently with polymer and functionalized with amino groups. By combining polyvinyl alcohol (PVA) and silica precursors, we were able to obtain silica-coated a ...
