Journal ArticleDOI
Bio-inspired hydrophobicity promotes CO 2 reduction on a Cu surface
David W. Wakerley,Sarah Lamaison,François Ozanam,Nicolas Menguy,Dimitri Mercier,Philippe Marcus,Marc Fontecave,Victor Mougel,Victor Mougel +8 more
TL;DR: Hydrophobicity is proposed as a governing factor in CO2 reduction selectivity and can help explain trends seen on previously reported electrocatalysts.
Journal ArticleDOI
Semiquantitative Study of the EDC/NHS Activation of Acid Terminal Groups at Modified Porous Silicon Surfaces
S. Sam,Larbi Touahir,J. Salvador Andresa,Philippe Allongue,J.-N. Chazalviel,Anne Chantal Gouget-Laemmel,C. Henry de Villeneuve,Anne Moraillon,François Ozanam,Noureddine Gabouze,S. Djebbar +10 more
TL;DR: This work rationalizes the different reaction paths and optimize the reaction conditions to obtain as pure as possible succinimidyl ester-terminated surfaces and maps the surface composition after activation was constructed by systematically varying the solution composition.
Journal ArticleDOI
Organic monolayers on Si(111) by electrochemical method
Philippe Allongue,C. Henry de Villeneuve,Jean Pinson,François Ozanam,J.-N. Chazalviel,Xavier Wallart +5 more
TL;DR: In this article, the formation of organic monolayers on Si(111) by electrochemical methods was studied and it was shown that grafting of phenyl groups is possible by reduction of + N 2 -Ar-X cations where the substituent X may be Br, NO 2, COOH, CN, C n H 2 n +1 (n = 1, 4, 12).
Journal ArticleDOI
Well-Defined Carboxyl-Terminated Alkyl Monolayers Grafted onto H−Si(111): Packing Density from a Combined AFM and Quantitative IR Study
A. Faucheux,Anne Chantal Gouget-Laemmel,Catherine Henry de Villeneuve,Rabah Boukherroub,François Ozanam,and Philippe Allongue,Jean-Noël Chazalviel +6 more
TL;DR: Results prove that neither surface oxidation nor grafting through the carboxyl end groups occurs, and complementary electrochemical impedance measurements indicate the excellent electronic properties of the interface with a very low density of gap states.
Journal ArticleDOI
In Situ Fourier‐Transform Electromodulated Infrared Study of Porous Silicon Formation: Evidence for Solvent Effects on the Vibrational Linewidths
TL;DR: In this article, an experimental investigation of porous silicon layer (PSL) formation and silicon/hydrofluoric acid interfaces, using internal-reflection Fourier-transform infrared spectroscopy and Fourier−transform electrochemically modulated infrared spectrum, was conducted.
