In the recent years, considerable progress has been made in iodine uptake—a radioactive emission process accompanying nuclear fission with porous organic polymers (POPs).
Many nonprecious metal-selenide-based materials have been reported as electrocatalysts with high activity for the oxygen evolution reaction (OER). Herein, a hybrid catalyst film composed of Cu2Se and Cu2O nanoparticles directly grown on Ti foil (Cu2Se-Cu2O/TF) was prepared through simple fast cathodic electrodeposition method. Surprisingly, this electrode required relatively low overpotential 465 mV to achieve catalytic current density 10 mA cm-2 OER in 0.2 M carbonate buffer (pH = 11.0)....
Abstract A series of MCM‐41s with a high copper content were synthesized at room temperature from sodium metasilicate (Na 2 SiO 3 ) as the silicon source, tetraamminecopper( II nitrate [Cu(NH 4 (NO ] source and cetyltrimethylammonium bromide (CTABr) template. The resulting material was characterized by using following characterization techniques: X‐ray diffraction (XRD), N ‐adsorption isotherms, high‐resolution transmission electron microscopy (HRTEM), inductively coupled plasma (ICP),...
Abstract The thermal transformations of kaolinite have been studied using 27 Al and 29 Si magic angle spinning nuclear magnetic resonance (MAS NMR), X-ray diffraction (XRD), differential analysis (DTA) thermogravimetric (TG). experimental results show that this sample is a pure which contains ∼3% carbonaceous material as impurity. MAS NMR spectra the microstructural evolution transformation at 450 –1050ºC similar to kaolinite– mullite reaction series previously published by many authors....
Four 1,6-disubstituted pyrene-based fluorescent conjugated microporous polymers were synthesized by Sonogashira–Hagihara reaction, trimerization reaction of –CN, and Friedel–Crafts respectively, which can efficient capture sense I<sub>2</sub>.
Abstract Three flexible oxygen‐bridged porous organic polymers (TPG, HCCPA, and HPG) have been synthesized by nucleophilic substitution polymerization reactions. The three POPs display efficient reversible adsorption of radioactive I 2 in vapor solution. In iodine at 350 K, the maximum capacities TPG, HPG are 5.29, 4.08, 1.63 g −1 , respectively. strong affinities for mainly due to charge transfer iodine. Interestingly, with decrease adsorption, complexes exhibit liquid, semi‐solid, solid...
