Micro-/nanocapsules have received substantial attention due to various potential applications for storage, catalysis, and drug delivery. However, their conventional enclosed non-/polycrystalline walls pose huge obstacles for rapid loading and mass diffusion. Here, the authors present a new single-crystal capsular-MOF with openings on the wall, which is carefully designed at the mol. level and constructed from a crystal-structure transformation. This rare open-capsule MOF can easily load the largest amounts of S and I among known MOFs. Derived from capsular-MOF and melamine through pyrolysis-phosphidation, the authors fabricated a N-doped capsular C-based framework with Fe-Ni phosphide nanoparticles immobilized on capsular carbons interconnected by plentiful carbon nanotubes. Benefiting from synergistic effects between the C framework and highly surface-exposed phosphide sites, the material exhibits efficient multifunctional electrocatalysis for O evolution, H evolution, and O reduction, achieving well-qualified assemblies of an overall H2O splitting (low potential of 1.59 V at 10 mA cm-2) and a rechargeable Zn-air battery (high peak power d. of 250 mW cm-2 and excellent stability for 500 h), which afford remarkably practical prospects over previously known electrocatalysts. In the experimental materials used by the author, we found 4-Acetylpyridine(cas: 1122-54-9Application In Synthesis of 4-Acetylpyridine)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.Application In Synthesis of 4-Acetylpyridine
