A multifaceted approach was presented to study H2 adsorption in both copper- and silver-exchanged SSZ-13 and for comparison the host framework SSZ-13. Low-pressure gas adsorption measurements revealed an increased H2 uptake in the cation-exchanged zeolites ...
Using high-throughput instrumentation to screen conditions, the reaction between FeCl2 and H3BTT·2HCl (BTT3- = 1,3,5-benzenetristetrazolate) in a mixt. of DMF and DMSO gave Fe3[(Fe4Cl)3(BTT)8]2·22DMF·32DMSO·11H2O. This compd. adopts a porous three-dimensio ...
The effect of poly(acrylic acid) (PAA), poly(vinylpyrrolidone) (PVP), sodium dodecylsulfate (SDS), hydroxypropylmethylcellulose (HPMC), and D-fructose additives on the growth of BaTiO3 particles by aqueous synthesis is studied. Through different mechanisms ...
The use of zeolites for catalytic reactions is a field in continuous development. Since it was demonstrated that metal-zeolites are efficient catalysts for NOx abatement, decomposition of nitrous oxide (N2O) over Fe-containing zeolites has attracted great ...
Density functional calculations applying periodic boundary conditions have been performed to investigate adsorption and cracking of light alkanes (C 3-C 6) on zeolite H-ZSM-5. Intrinsic energy barriers were obtained from single-point calculations by applyi ...
Typical flue gas streams have low concns. of CO2 and high gas flow rates, making porous materials, such as zeolites, metal-org. frameworks (MOFs), and activated carbons promising options for the future sepn./sequestration of CO2. These framework materials ...
Monte Carlo (MC) simulations are commonly used to obtain adsorption properties of gas molecules inside porous materials. In this work, we discuss various optimization strategies that lead to faster MC simulations with CO 2 gas molecules inside host zeolite ...
Copper and silver cation-exchanged zeolite SSZ-13 present an interesting opportunity to study the mechanism of interaction of adsorbate gases, primarily hydrogen (H2), with the ion-exchange sites in zeolites as there is only one type of cation site, in con ...
Block-copolymer templating of inorg. frameworks provides a powerful route to produce periodic nanoporous materials with well-defined nanoscale architectures, controlled porosity, and high surface area. Such control is important for batteries and pseudocapa ...
It is shown that surface NMR spectra can be greatly enhanced using dynamic nuclear polarization. Polarization is transferred from the protons of the solvent to the rare nuclei (here carbon-13 at natural isotopic abundance) at the surface, yielding at least ...
