Comprehensive Summary Polyhydroxyurethanes (PHUs) have received considerable attention in the last decade as potential alternatives to traditional phosgene‐based polyurethanes (PUs). The development of suitable 5CC (five membered‐ring cyclic carbonate) precursors bearing multiple carbonate moieties (multi‐5CCs) is a key requisite for preparing PHUs by polyaddition reaction with bis‐ or polyamines. Producing sustainable from CO 2 ‐based five‐membered carbonates (5CCs) obtained biobased...
ZnO/SiO2 core/shell particles were prepared by the hydrolysis and condensation of tetraethyl orthosilicate on ZnO nanoparticles (particle size ca. 50–200 nm) nanorods (diameter 124 nm length 400–950 nm). The silica shell thickness was varied (28 to 40 adjust composition (Si/Zn ratio) reiterating coating procedure. Heat treatment nanoparticle/SiO2 with suitable stoichiometry ratio 0.5) at 1000 °C resulted in formation single-phase Zn2SiO4 as hollow particles. use different morphologies (ZnO...
ZnO nanostructures were synthesized by a combination of non-aqueous and aqueous sol-gel techniques to obtain morphologically different nanostructures, nanorods, nanopyramids, featuring oxygen vacancies-rich exposed lattice faces exhibiting catalytic properties activity. In particular, nanorods with high surface area (36 m2/g) obtained through rapid, scalable, convenient procedure. The materials tested for complete methane oxidation as an important benchmark reaction that is sensitive the...
Atomically dispersed cerium catalysts on an inert, crystalline MgO powder support were prepared by using both Ce(III) and Ce(IV) precursors. The materials used as for CO oxidation in a once-through flow reactor characterized atomic-resolution scanning transmission electron microscopy, X-ray absorption near-edge structure spectroscopy, photoelectron temperature-programmed reduction, among other techniques, before after catalysis. most active catalysts, formed from the precursor incorporating...
