Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Karima Baghdad, Mohammed Abdelkrim Hasnaoui, Franck Launay

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt,…

On the Comprehensive Precipitation of Hydroxyapatites Unraveled by a Combined Kinetic–Thermodynamic Approach

Corentin Reynaud, Cyril Thomas, Guylène Costentin

The present study combines experimental and theoretical approaches to investigate the competitive precipitation of calcium phosphates (CaPs) in aqueous solution in order to understand and control both the structural and textural properties of the synthesized hydroxyapatites (HAps). Some of the…

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…

Particle Size Effects in the Selective Hydrogenation of Alkadienes over Supported Cu Nanoparticles

Giorgio Totarella, Jan Willem de Rijk, Laurent Delannoy, Petra de Jongh

Copper is considered an excellent alternative to noble-metal selective hydrogenation catalysts. Herein, we systematically studied the effect of Cu nanoparticle size (2-10 nm) in the selective hydrogenation of 1,3-butadiene in excess of propene. The catalysts exhibited particle size-dependent…

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-…
