Hydrophobic zeolitic imidazolate frameworks (ZIFs) with the chabazite (CHA) topology are synthesized by incorporating two distinct imidazolate links. Zn(2-mIm)0.86 (bbIm)1.14 (ZIF-300), Zn(2-mIm)0.94 (cbIm)1.06 (ZIF-301), and Zn(2-mIm)0.67 (mbIm)1.33 (ZIF-302), where 2-mIm = 2-methylimidazolate, bbIm = 5(6)-bromobenzimidazolate, cbIm = 5(6)-chlorobenzimidazolate, and mbIm = 5(6)-methylbenzimida...
Nonlocal periodic density functional calculations have been used to examine the stability of various possible reactive intermediates resulting from the initial adsorption of methanol in the zeolite chabazite. The formation of dimethyl ether has been examined both for pathways via framework coordinated methyl groups and by direct condensation with the framework acting as a solvent. Both are foun...
Retention mechanism of cesium in chabazite embedded into metakaolin-based alkali activated materials
Disposal of cesium-137 (Cs-137)-loaded chabazite generated from decontaminating cooling water the damaged reactor at Fukushima Daiichi Nuclear Power Station (FDNPS) has become a crucial concern. The potassium aluminosilicate-based alkali activated material (K-AAM) matrix is one candidate encapsulation matrices proposed for encapsulating cesium-137. In this study, loaded with low Cs concentratio...
