The search for efficient water oxidation catalysts (WOCs) is of paramount importance in energy and environmental fields, but there exists no good non-noble catalyst that works under acidic and alkaline conditions. Intensive investigations have recently focused on cobalt based complex/solid catalysts. Here, we have introduced a new type of cobalt-based WOC made of metal-organic frameworks where ...

Enlargement of micropores in zeolitic imidazolate framework particles into mesopores is achieved via an ethylene glycol-assisted aqueous etching method. The etched carbon shows a higher specific capacitance than unetched one at high scan rates.

Zeolitic imidazolate frameworks (ZIFs) are a new class of nanoporous compounds which consist of tetrahedral clusters of MN4 (M ) Co, Cu, Zn, etc.) linked by simple imidazolate ligands.1,2 As a subfamily of metal-organic frameworks (MOFs), ZIFs exhibit the tunable pore size and chemical functionality of classical MOFs. At the same time, they possess the exceptional chemical stability and rich st...

Hidden Zeolitic Imidazolate Frameworks In article number 2300036, David ChangMo Yang, Wonyoung Choe, and co-workers propose a library of 207 future zeolitic imidazolate frameworks (ZIFs) from over 2,000,000 zeolites guided by intuition-based geometrical descriptors. Carefully chosen structural descriptors facilitate the prediction new ZIFs. The collection plausible ZIFs serves as blueprint for ...

Hydrogen storage in porous materials gained considerable interest, since in the past 15 years many new coordination polymers or framework materials have been synthesized, which show a permanent ultra-high porosity and an extremely large specific surface area [1-3]. Different classes of these novel highly porous structures, e.g., metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (...

We evaluate the self-diffusion and transport diffusion of interacting particles in a discrete geometry consisting of a linear chain of cavities, with interactions within a cavity described by a free-energy function. Exact analytical expressions are obtained in the absence of correlations, showing that the self-diffusion can exceed the transport diffusion if the free-energy function is concave. ...
