Carbon dioxide sensitivity of zeolitic imidazolate frameworks.
Zeolitic imidazolate frameworks of zinc, cobalt, and cadmium, including the framework ZIF-8 commercially sold as Basolite Z1200, exhibit surprising sensitivity to carbon dioxide under mild conditions. The frameworks chemically react with CO2 in the presence of moisture or liquid water to form carbonates. This effect, which has been previously not reported in metal-organic framework chemistry, p...
متن کاملControl over Porosity using Isoreticular Zeolitic Imidazolate Frameworks (IRZIFs) as Template for Porous Carbon Synthesis
Herein, using Isoreticular Zeolitic Imidazolate Frameworks (IRZIFs) as template, we report the synthesis, morphology and gas adsorption properties of porous carbon synthesized by nanocasting method at 1000 C, where furfuryl alcohol (FA) has been used as a carbon source. Using IRZIFs with variable porosity as templates, we could achieve the control over carbon porosity, H2 and CO2 uptake. The r...
متن کاملSynthesis, structure, and carbon dioxide capture properties of zeolitic imidazolate frameworks.
Zeolites are one of humanity's most important synthetic products. These aluminosilicate-based materials represent a large segment of the global economy. Indeed, the value of zeolites used in petroleum refining as catalysts and in detergents as water softeners is estimated at $350 billion per year. A major current goal in zeolite chemistry is to create a structure in which metal ions and functio...
متن کاملSolution mediated phase transformation (RHO to SOD) in porous Co-imidazolate based zeolitic frameworks with high water stability.
Here we report a highly porous, water stable Co based ZIF [CoNIm (RHO)] and its solution mediated phase transformation to a less porous and water unstable ZIF [CoNIm (SOD)]. CoNIm (RHO) has high Langmuir surface area [2087 m(2) g(-1)] as well as high water adsorption [200 cm(3) (STP) g(-1)] capacity.
متن کاملZeolitic imidazolate frameworks for kinetic separation of propane and propene.
Propane/propene separation by cryogenic distillation is one of the most energy and cost intensive industrial processes. Adsorptive separation is a more energy-efficient alternative. Three isostructural zinc imidazolate zeolitic framework materials are found, for the first time, to be very promising in the separation of propene and propane based on their different diffusion rates. Fine-tuning of...
