Hydrothermally stable Pd/SiO2@Zr Core@Shell catalysts for diesel oxidation applications

Chih-Han Liu, Junjie Chen, Todd Toops, Jae-Soon Choi, Cyril Thomas, Michael Lance, Eleni Kyriakidou

Hydrothermally stable diesel oxidation catalysts (DOCs) with improved low-temperature activity are desired for the abatement of emissions from diesel vehicles. Herein, novel palladium(Pd)/SiO2(core)@Zr(shell) structured DOCs were developed. SiO2 was completely covered by an 8.4 nm thickness Zr-…

Tough thiourethane thermoplastics for fused filament fabrication

Gregory Ellson, Xavier Carrier, Jamie Walton, Samsuddin Faisal Mahmood, Kejia Yang, Joshua Salazar, Walter Voit

Fused filament fabrication (FFF) is the most common form of additive manufacturing. Most FFF materials are variants of commercially available engineering plastics. Their performance when printed can widely vary, thus there is an increasing volume of research on alternative materials with thermal…

Optimization of Synthesis Conditions of Ni/SBA-15 Catalysts: Confined Nanoparticles and Improved Stability in Dry Reforming of Methane

Nissrine El Hassan, Marie-Nour Kaydouh, Nissrine El, Anne Davidson, Pascale Massiani

Despite its economic and environmental advantages, the dry reforming of methane using supported Ni-based catalysts remains challenging due to problems of metal particle sintering and carbon deposition, which lead to loss in catalytic activity. In this study, different silica supports, containing 5…

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…

EIS investigations of the oxygen reduction reaction at the cathode of an enzymatic biofuel cell

Achraft Blout, Florence Billon, Hubert Perrot, Claude Jolivalt, Alain Pailleret

Enzymatic biofuel cells (EBCs) have been extensively studied over the last ten years in view of their application as implantable devices [1,2] as they have been shown indeed to reach the power required for small electronic devices. In EBCs, redox reactions occurring at the cathode and the anode are…

Development of a thermodynamic approach to assist the control of the precipitation of hydroxyapatites and associated calcium phosphates in open systems

Corentin Reynaud, Cyril Thomas, Sandra Casale, Sophie Nowak, Guylène Costentin

The understanding of the precipitation mechanisms of calcium phosphates (CaPs) remains extremely challenging despite its fundamental interest for material sciences and its practical implications in medicine, paleosciences, and chemistry, especially for heterogeneous catalysis. The competitive…

Ni/CeO2 Nanoparticles Promoted by Yttrium Doping as Catalysts for CO2 Methanation

Valeria La Parola, Chao Sun, Patricia Beaunier, Leonarda F Liotta, Patrick da Costa

Ni (5 wt.%) catalysts over yttrium modified CeO2 oxides synthesized by hydrothermal method were prepared. For comparison Ni was supported over pure CeO2 and Y2O3. Characterizations by N2 adsorption/desorption, XRD, XPS, TEM/HRTEM, H2-TPR, CO2-TPD and TGA were carried out. The catalytic performance…

Activity of molybdenum and tungsten oxycarbides in hydrodenitrogenation of carbazole leading to isomerization secondary reaction of bicyclohexyl. Results using bicyclohexyl as feedstock

Marek Lewandowski, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activities of bulk tungsten and molybdenum oxycarbides, (W2C and Mo2C) have been specifically studied in the isomerization occurring during the hydrodenitrogenation (HDN) of carbazole. The two catalysts have been characterized by several physico-chemical techniques such as X-Ray…
