“…Mechanical agitation is not alwaysn ecessary in this approach,a sd emonstrated by crystallization of dryp recursor mixtures of metal oxides or hydroxidesa nd azole-basedl inkers induceds olely by thermalt reatment. [17] Precursor mobility is in this case promoted by the fluid medium through melting, evaporation, or sublimation of the linker.S toichiometricf ormation of fluid molecules by protonation of metal precursor counter anions likely plays an important role as well.…”

Materials processing, and thin-film deposition in particular, is decisive in the implementation of functional materials in industry and real-world applications. Vapor processing of materials plays a central role in manufacturing, especially in electronics. Metal-organic frameworks (MOFs) are a class of nanoporous crystalline materials on the brink of breakthrough in many application areas. Vapor deposition of MOF thin films will facilitate their implementation in micro- and nanofabrication research and industries. In addition, vapor-solid modification can be used for postsynthetic tailoring of MOF properties. In this context, we review the recent progress in vapor processing of MOFs, summarize the underpinning chemistry and principles, and highlight promising directions for future research.

“…The one-pot synthesis of the ZIF-based electrocatalyst precursor was carried out according to previously reported procedures [17,27]. Preparation of Zn(mIm)2TPI was carried out by adding 2-methylimidazole (668.2 mg, 8 mmol, Aldrich, St. Louis, MO, USA), ZnO (323.5 mg, 4 mmol, Aldrich), and 0.022 mol % iron in the form of 1,10-phenanthroline iron (II) perchlorate (70.5 mg, 0.09 mmol, Aldrich) together, grinding, and sealing in an autoclave under an Ar atmosphere.…”

Abstract:Finding inexpensive alternatives to platinum group metals (PGMs) is essential for reducing the cost of proton exchange membrane fuel cells (PEMFCs). Numerous materials have been investigated as potential replacements of Pt, of which the transition metal and nitrogen-doped carbon composites (TM/Nx/C) prepared from iron doped zeolitic imidazolate frameworks (ZIFs) are among the most active ones in catalyzing the oxygen reduction reaction based on recent studies. In this report, we demonstrate that the catalytic activity of ZIF-based TM/Nx/C composites can be substantially improved through optimization of synthesis and post-treatment processing conditions. Ultimately, oxygen reduction reaction (ORR) electrocatalytic activity must be demonstrated in membrane-electrode assemblies (MEAs) of fuel cells. The process of preparing MEAs using ZIF-based non-PGM electrocatalysts involves many additional factors which may influence the overall catalytic activity at the fuel cell level. Evaluation of parameters such as catalyst loading and perfluorosulfonic acid ionomer to catalyst ratio were optimized. Our overall efforts to optimize both the catalyst and MEA construction process have yielded impressive ORR activity when tested in a fuel cell system.
