Investigation of ion-selective electrodes with neutral ionophores and ionic sites by EIS. II. Application to K+ detection

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

The impedance of an ion-selective electrode (ISE) to potassium with valinomycin as the ionophore and KBΦ4 as the ionic sites was measured. The membrane was made of PVC with DNP as a plasticizer. The influence of the content of the plasticizer and the membrane thickness was investigated. The…

Control of calcium accessibility over hydroxyapatite by post-precipitation steps: influence on the catalytic reactivity toward alcohols

Manel Ben Osman, Sarah Diallo Garcia, Jean-Marc Krafft, Christophe Methivier, Juliette Blanchard, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Hydroxyapatites are increasingly used as heterogeneous catalysts since they present atypical behaviours for many acid base reactions. The aim of this study was to discuss the possible involvement of Ca2+ Lewis and/or PO–H Brønsted acid sites belonging to the hydroxyapatite system in the conversion…

Discrimination of Surface and Bulk Structure of Crystalline Hydroxyapatite Nanoparticles by NMR

Manel Ben Osman, Sarah Diallo-Garcia, Virginie Herledan, Dalil Brouri, Tetsuya Yoshioka, Jun Kubo, Yannick Millot, Guylène Costentin

Solid state 1H and 31P NMR spectroscopy was used to characterize well-crystallized hydroxyapatite samples of different stoichiometry prepared by a precipitation route. The aim of the paper was to investigate the bulk structural features of samples with different stoichiometry and to discriminate…

General and Prospective Views on Oxidation Reactions in Heterogeneous Catalysis

Sabine Valange, Jacques C. Védrine

In this review paper, we have assembled the main characteristics of partial oxidation reactions (oxidative dehydrogenation and selective oxidation to olefins or oxygenates, as aldehydes and carboxylic acids and nitriles), as well as total oxidation, particularly for depollution, environmental…

Sn-BEA zeolites prepared by two-step postsynthesis method: Physicochemical properties and catalytic activity in processes based on MPV reduction

Nataliia Popovych, Pavlo Kyriienko, Yannick Millot, Laetitia Valentin, Jacek Gurgul, Robert Socha, Jan Żukrowski, Sergiy Soloviev, Stanislaw Dzwigaj

Sn0.5SiBEA and Sn2.0SiBEA zeolites obtained by two-step postsynthesis method were characterized by several physicochemical techniques (namely, NMR, Mössbauer, XPS, DR UV-vis and IR spectroscopies) and used in the study of Meerwein–Ponndorf–Verley (MPV) reduction as well as with the subsequent…

Impact of Mn addition on catalytic performance of Cu/SiBEA materials in total oxidation of aromatic volatile organic compounds

Anna Rokicińska, Patrycja Majerska, Marek Drozdek, Sebastian Jarczewski, Laetitia Valentin, Jianhong Chen, Adam Slabon, Stanislaw Dzwigaj, Piotr Kuśtrowski

Dealuminated BEA zeolite (SiBEA) was chosen as a support of metal oxide(s) phase for catalytic combustion of volatile organic compounds (VOCs). Copper and/or manganese oxide(s) were deposited at various Cu/Mn molar ratios. Factors influencing the catalytic activity were found by chosen…

Time-resolved infrared absorption spectroscopy applied to photoinduced reactions: how and why

Alberto Mezzetti, Josefine Schnee, Andrea Lapini, Mariangela Di Donato

Time-resolved infrared (IR) spectroscopy is a widely used technique in the investigation of photoinduced reactions, given its capabilities of providing structural information about the presence of intermediates and the reaction mechanism. Despite the fact that it is used in several fields since the…
