Additive-Free Aqueous Phase Synthesis of Formic Acid by Direct CO 2 Hydrogenation over a PdAg Catalyst on a Hydrophilic N-Doped Polymer–Silica Composite Support with High CO 2 Affinity

Shinya Masuda, Kohsuke Mori, Yasutaka Kuwahara, Catherine Louis, Hiromi Yamashita

A series of N-doped polymer containing silica (NPS) materials were synthesized via condensation reactions of 3-aminopropyltriethoxysilane (APT) and various aldehydes. These materials were assessed as supports for a PdAg alloy catalyst intended to promote the CO2 hydrogenation reaction under…

Design of Advanced Functional Materials Using Nanoporous Single‐Site Photocatalysts

Kohsuke Mori, Xufang Qian, Yasutaka Kuwahara, Yu Horiuchi, Takashi Kamegawa, Yixin Zhao, Catherine Louis, Hiromi Yamashita

Nanoporous silica solids can offer opportunities for hosting photocatalytic components such as various tetra-coordinated transition metal ions to form systems referred to as “single-site photocatalysts”. Under UV/visible-light irradiation, they form charge transfer excited states, which exhibit a…

NO2 disproportionation for the IR characterisation of basic zeolites

Olivier Marie, Nicolas Malicki, Catherine Pommier, Pascale Massiani, Ann Vos, Robert Schoonheydt, Paul Geerlings, Carlos Henriquese, Frédéric Thibault-Starzyk

NO2 disproportionation on alkaline zeolites is used to generate nitrosonium (NO+) and nitrate ions on the surface, and the infrared vibrations observed are very sensitive to the cation chemical hardness and to the basicity of zeolitic oxygen atoms.side pockets of acidic mordenite. We describe here…

Vibrating single probe and stationary bi-probes to measure local electrochemical impedance spectroscopy.

Hisasi Takenouti, G. Galicia, Michel Keddam, Vincent Vivier

The electrochemical impedance spectroscopy is widely used to investigate the electrode kinetics. This method is recognized as a powerful method to discriminate one reaction model to another and also to evaluate the reaction rate of elementary steps. However, when the electrode kinetics is markedly…

Study of gold electrodissolution by scanning electrochemical microscopy in different modes

Divino Salvador Ramírez-Rico, Michel Keddam, Erika Roxana Larios-Durán, Vincent Vivier

The electrodissolution of gold has already been widely studied by several methods, but no consensus concerning the reaction mechanism has been reached. In this work, the scanning electrochemical microscopy (SECM) has been used in transient condition for studying the electrodissolution of gold in…

Surface-induced assembly of sophorolipids

Jessie Peyre, Ahmed Hamraoui, Marco Faustini, Vincent Humblot, Niki Baccile

The surface self-assembly properties of acidic sophorolipids, a bolaform microbial glycolipids with pH-responsive properties in solution, were studied based on the chemical nature of the support and pH of the solution. Sophorolipids generally form micelles in water but formation of morphologies…

Decoding anionic organization of hydroxide-fluorides in a diaspore-type network

Helies Hyrondelle, Matthew Suchomel, Vincent Rodriguez, Étienne Durand, Yannick Millot, Mathieu Duttine, Alain Demourgues

The diaspore-type crystalline structure is historically well-known in mineralogy, but it has also been widely studied for various applications in the field of catalysis, electrocatalysis, and batteries. However, once two anions of similar ionic size but different electronegativity, such as F– and…
