TL;DR: The Au@PION hybrid materials used as a heterogeneous catalyst were highly active, selective, and stable in the aerobic oxidation of saturated alcohols.
Abstract: Nanoporous ionic organic networks (PIONs) with a high ionic density 9 (three cation−anion pairs per unit) have been synthesized by a facile S N 2 nucleophilic 10 substitution reaction. Owing to the electrostatic and steric effect, those ionic networks 11 with porous channels can stabilize and support gold (Au) nanoparticles (NPs) in 1−2 12 nm. The Au@PION hybrid materials used as an heterogeneous catalyst were highly 13 active, selective, and stable in the aerobic oxidation of saturated alcohols. 14 KEYWORDS: Gold nanoparticles, gold catalysis, porous polyelectrolyte, porous poly(ionic liquid)s, aerobic oxidation 15 D uring the past decade, the possibility of modulating the 16 physicochemical properties of ionic liquids (ILs) by an 17 appropriate combination of cations and anions allied to their 18 supramolecular organization enables the ILs-mediated prepara- 19 tion of metallic nanoparticles (NPs). 1−5 Meanwhile, gold (Au) 20 NPs with increased fractions of edges and corners have been

TL;DR: In this article, ultrasmall polyacrylonitrile particles with controllable sizes are supported on poly(ionic liquid)s microspheres (PILMs/PAN) by epitaxial polymerization growth strategy.
Abstract: A small size effect could be conducive to enhancing the electrochemical performance, while the mechanism by which they also increase the capacitance for carbon electrode materials has not been established. Here, ultrasmall polyacrylonitrile particles with controllable sizes are supported on poly(ionic liquid)s microspheres (PILMs/PAN) by epitaxial polymerization growth strategy. Unlike traditional subtraction formulas in developing a porous architecture, we report on the synthesis of creating numerous micro/mesopores in carbon materials by addition theorem, and thus making for the perfection of packing density, which has not been reported yet. As an example, PILMC/PAN-L with a well-balanced specific surface area of 875.38 m2 g−1 and packing density of 1.05 g cm−3 demonstrated gravimetric and volumetric capacitances of 309 F g−1 and 324.45 F cm−3 at 0.5 A g−1, showing good rate performance and stable cyclability. Moreover, the underlying mechanism is thoroughly developed using multiple electrochemical methods. On this basis, this work would afford avenues to further enhancing the electrochemical performance, especially in exploring advanced carbon materials.
