PdAg alloy nanoparticles encapsulated in N-doped microporous hollow carbon spheres for hydrogenation of CO2 to formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

Here, we report a general synthesis approach to produce PdAg nanoparticles (NPs) that are dispersed uniformly within N-doped microporous hollow carbon spheres (NMHCS) for hydrogenation of CO2 to formate. The optimized PdAg@NMHCS catalyst, which was obtained by using an optimized amount of…

Unlocking synergy in bimetallic catalysts by core–shell design

Jessi van der Hoeven, Jelena Jelic, Liselotte Olthof, Giorgio Totarella, Relinde van Dijk-Moes, Jean-Marc Krafft, Catherine Louis, Felix Studt, Alfons van Blaaderen, Petra de Jongh

Extending the toolbox from mono- to bimetallic catalysts is key in realizing efficient chemical processes1. Traditionally, the performance of bimetallic catalysts featuring one active and one selective metal is optimized by varying the metal composition1,2,3, often resulting in a compromise between…

Rational design of a CO2-resistant toluene hydrogenation catalyst based on FT-IR spectroscopy studies

Julien Scalbert, Cécile Daniel, Yves Schuurman, Cyril Thomas, Frédéric C. Meunier

Rhodium highly dispersed on alumina becomes partly poisoned by strongly bound CO when used for toluene hydrogenation at 348 K in the presence of CO2. Operando FT-IR analysis enabled to observed CO(ads) build up over the sample, while no CO(gas) could be measured in the reactor effluent. Analyses…

Copper incorporated mesoporous materials: synthesis, characterization and catalytic activity in benzaldehyde reduction

O. Zekri, A. Saadi, F. Launay, C. Calers, C. Rabia

Copper substituted mesoporous silica materials (Cu–HMS-n), with a variety of Si/Cu atomic ratios (n) ranging from 50 to 100, were synthesized by the one-pot sol–gel method using dodecylamine as template. These materials were characterized by X-ray diffraction, N2 adsorption-desorption, transmission…

Dealuminated Beta Zeolite Modified by Alkaline Earth Metals

Karolina Chalupka, Renata Sadek, Laetitia Valentin, Yannick Millot, Christophe Calers, Magdalena Nowosielska, Jacek Rynkowski, Stanislaw Dzwigaj

Alkaline Earth metals (Mg, Sr, and Ca) were incorporated into the dealuminated mesoporous beta zeolite (DeAlBeta) by the two-step postsynthesis method. Physicochemical properties of both unmodified and alkaline Earth metal-modified DeAlBeta zeolite were characterized by XRD, DR UV-vis, FTIR, TPD of…

Molecular Understanding of the Bulk Composition of Crystalline Nonstoichiometric Hydroxyapatites: Application to the Rationalization of Structure-Reactivity Relationships

Manel Ben Osman, Jean Marc Krafft, Yannick Millot, Frederic Averseng, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Crystalline hydroxyapatite samples (HAps) have been prepared by using the co-precipitation method under various pH conditions, leading to nonstoichiometric solids (1.65 < Ca/P < 1.77). The aim of this study was to rationalize the sensitivity of the catalytic activity of HAps to their bulk…
