Unravelling surface changes on Cu-Ni alloy upon immersion in aqueous media simulating catalytic activity of aerobic biofilms

Nesrine Aissaoui, Irma Liascukiene, Michel Genet, Christine Dupont-Gillain, Karim El Kirat, Caroline Richard, Jessem Landoulsi

Cu-Ni alloys are extensively used in contact with natural waters and are impacted by microbial activities of biofilms. The mechanisms by which surface changes occur upon immersion remain not well understood. Herein, an aerobic microbial activity of natural biofilms is mimicked by the enzymatic…

Diagnosis of the Diatom Community upon Biofilm Development on Stainless Steels in Natural Freshwater

Caroline Richard, Smita Mitbavkar, Jessem Landoulsi

This paper reports the development of biofilms on stainless steels (SS) upon exposure in a natural freshwater ecosystem for about six months and focuses on the composition of diatom populations. By using environmental scanning electron microscopy (ESEM) technique, we provide a detailed description…

Tuning covalence for phosphorus-mediated C-C coupling in carbon monoxide electroreduction to multicarbon oxygenates

Anissa Ghoridi, Carlos V M Inocêncio, Hong Phong Duong, Ngoc-Huan Tran, Zubair Ahmed, Isabel Gómez-Recio, Maria Luisa Ruiz-Gonzàlez, Stephan Steinmann, Preeti Verma, Claudia Morais, Nadia Guignard, Antoine Miche, Sandra Casale, Christel Gervais, Cristina Coelho Diogo, Isabelle Génois, Andrea Zitolo, Christoph Sahle, Alessandro Longo, José Maria González-Calbet, Marc Fontecave, David Portehault

Electrochemical carbon monoxide reduction (COR) is a promising route for sustainable production of multicarbon chemicals from CO2, as it bypasses the large carbon losses of direct CO2 electroreduction. In most electrocatalysts currently explored to tune COR selectivity towards highadded value…

Fe3+-doped ordered mesoporous γ-Fe2O3/SiO2 microspheres as a highly efficient magnetically separable heterogeneous Fenton catalyst

Nassira Ferroudj, Patricia Beaunier, Anne Davidson, Sébastien Abramson

Here, several γ-Fe 2 O 3 /SiO 2 nanocomposite microspheres were synthesized, characterized and tested as magnetically separable heterogeneous catalysts in an advanced oxidation process. A strong relation between the structure and the activity of these materials was evidenced. Two parameters,…

Bi2O3, BiVO4, and Bi2WO6: Impact of Surface Properties on Photocatalytic Activity under Visible Light

Tamar Saison, Nicolas Chemin, Corinne Chaneac, Olivier Durupthy, Valerie Ruaux, Laurence Mariey, Françoise Mauge, Patricia Beaunier, Jean-Pierre Jolivet

Bismuth-based oxides have attractive photocatalytic properties under visible light. A better understanding of the origin of that good photocatalytic activity should allow its control and its optimization. In this Article, we have studied the impact of surface properties on photocatalytic activity…

Revealing Size Dependent Structural Transitions in Supported Gold Nanoparticles in Hydrogen at Atmospheric Pressure

Abdallah Nassereddine, Qing Wang, David Loffreda, Christian Ricolleau, Damien Alloyeau, Catherine Louis, Laurent Delannoy, Jaysen Nelayah, Hazar Guesmi

The enhancement of the catalytic activity of gold nanoparticles with their decreasing size is often attributed to the increasing proportion of low-coordinated surface sites. This correlation is based on the paradigmatic picture of working gold nanoparticles as perfect crystal forms having complete…

EIS measurements in molecular electronics

Meiling Su, Kieu Ngo, Jean-Christophe Lacroix, Mireille Turmine, Vincent Vivier

Although electrochemical impedance spectroscopy (EIS) has already demonstrated its reliability in electrochemistry and organic semiconductors as a tool for tracking charge-carrier transport, its potential in molecular electronics has not yet been fully realized. In this emerging field, where DC…
