A metal–organic framework functionalized with piperazine exhibiting enhanced CH₄ storage

Abstract

NJU-Bai 19, the first cycloaliphatic ring (piperazine) functionalized MOF-505 analogue, exhibits a notably high methane storage capacity of 246 cm3 (STP) cm−3 (at room temperature and 65 bar) and a working capacity of 185 cm3 (STP) cm−3.

Porous carbon with large surface area derived from a metal–organic framework as a lithium-ion battery anode material

“…An appealing structural feature is that the 2D layers are stacked in an ABAB fashion without interpenetration ( Fig. 1e), giving a 1D channel with the effective pore size of 8.7 Â 8.7Å 2 (Fig. 1f).…”

“…1 There is more and more interest in developing anode materials with high specic capacity and excellent cycle reversibility for next generation high-energy density rechargeable LIBs. 2 Due to their good safety, stability and large electrical conductivity, porous carbonaceous composites have recently been found to have great potential as electrode materials. However, traditional commercial graphite materials with a capacity of only 372 mA h g À1 cannot meet the demands of high-energy density power batteries.…”

Evolution of the Design of CH4 Adsorbents

“…NJU-Bai 19 has a working capacity of 246.6 cm 3 (STP) cm −3 at room temperature and 65 bar. In addition, NJU-Bia 19 has low isosteric heat of adsorption that may decrease the cost and complexity associated with methane uptake and delivery management [77]. The low isosteric heat decreases the effect of the change in temperature on the deliverable capacity, providing wider temperature ranges for operation.…”

Ultra‐small and highly dispersed Pd nanoparticles inside the pores of ZIF‐8: Sustainable approach to waste‐minimized Mizoroki–Heck cross‐coupling reaction based on reusable heterogeneous catalyst

“…MOFs are crystalline hybrid porous compounds which are formed by self‐assembly and bridging of metal ions and organic linkers to form one‐, two‐ and three‐dimensional networks . Because of the outstanding chemical and physical properties of MOFs, they have become highly promising candidates for a variety of applications including gas sensing, gas storage, chromatographic separation, drug delivery, biosensing and heterogeneous catalysis . Among the MOFs, the zeolitic imidazolate framework (ZIF‐8) is a subclass, which consists of zinc ions linked by 2‐methylimidazole ligands (Zn(MeIM) 2 ; MeIM = 2‐methylimidazole).…”
