Because the micro/nanoscale structure has a great potential to overcome the disadvantages of low specific surface area (SSAs) and poor contacts of active materials with electrolyte/pollutants compared to conventional bulks or aggregate materials.…”

In this paper, the Ni/NiO ultrathin nanobelts were successively synthesized by a facile in suit conversion process using pre-synthesized Ni-based metal-organic frameworks (MOFs) nanobelts as parent materials to detect the nitrite (NaNO 2 ). The synthesized Ni/NiO composites have the advantages in structure, as follows: (I) Interleaved 3D reticulated structure has strong mechanical stability; (II) Ultrathin nanobelt structures allow more active sites to be exposed and make the transfer of charge faster; (III) A large number of ultrafine Ni nanoparticles decorate the building blocks of the NiO nanobelt and enhance the electrical conductivity. Ni/NiO/GCE has an obvious oxidation peak at 0.78 V, when the concentration is between 0.5 and 1000 µM, the oxidation peak current of NaNO 2 is linearly related to the concentration, and the sensitivity is 1.5319 µA mM −1 cm −2 (S/N = 3). Moreover, the experimental results also concluded that the Ni/NiO ultrathin nanobelts not only indicated wonderful reproducibility in the determination of NaNO 2 in the pickled pork samples, but also could be well-recovered and keep stable for a long time.Keywords: in suit conversion method, Ni/NiO ultrathin nanobelt, metal nanoparticle, metal organic framework, nitrite

“…[4] Adsorption-based separation will be an important technology for the future C 2 H 2 /CO 2 separation. There has been as harp increase in the study on crystalline porous materials in the past 30 years,especially on metal-organic frameworks (MOFs) [6,7] because of the diverse selection of organic ligands and metal ions/clusters. How to simultaneously increase adsorption capacity, selectivity,a sw ell as the stability of the adsorbents is ab ottleneck.…”

Ultramicroporous Building Units as a Path to Bi‐microporous Metal–Organic Frameworks with High Acetylene Storage and Separation Performance

As trategy called ultramicroporous building unit (UBU) is introduced. It allows the creation of hierarchical biporous features that work in tandem to enhance gas uptake capacity and separation. Smaller pores from UBUs promote selectivity,w hile larger inter-UBUp acking pores increase uptake capacity.T he effectiveness of this UBUs trategy is shown with ac obalt MOF (denoted SNNU-45) in which octahedral cages with 4.5 pore sizeserve as UBUs.The C 2 H 2 uptake capacity at 1atm reaches 193.0 cm 3 g À1 (8.6 mmol g À1 ) at 273 Kand 134.0 cm 3 g À1 (6.0 mmol g À1 )at298 K. Suchhigh uptake capacity is accompanied by ahigh C 2 H 2 /CO 2 selectivity of up to 8.5 at 298 K. Dynamic breakthrough studies at room temperature and 1atm show aC 2 H 2 /CO 2 breakthrough time up to 79 min g À1 ,among top-performing MOFs.Grand canonical Monte Carlo simulations agree that ultrahigh C 2 H 2 /CO 2 selectivity is mainly from UBUultramicropores,while packing pores promote C 2 H 2 uptake capacity.

“…Noticeably, in each independent set of [Zn(L)(NO 2 pbda)] n , the NO 2 pbda 2− ligands act as linear ligands to link two Zn(II) atoms by the opposite carboxylate groups in the µ 1 -η 1 :η 0 -monodentate mode, forming a one-dimensional (1D) chain [Zn(NO 2 pbda)] n . The linear L ligands connect 1D chains into two-dimensional (2D) [Zn(L)(NO 2 pbda)] n layers (Figure 1b), which can be considered as 4 4 -sql topology, by taking Zn(II) atoms as 4-connecting nodes, and the L and NO 2 pbda 2− ligands as 2-connectors. Thus, two L ligands together with two NO 2 pbda 2− units, connect four Zn(II) atoms to afford a [Zn 4 (L) 2 (NO 2 pbda 2− ) 2 ] square unit, where the lateral Zn•••Zn distances are around 9.10 and 13.36 Å.…”

Two interpenetrated coordination polymers (CPs) {[Zn1(L)(NO2pbda)]n[Zn2(L)(NO2pbda)]n} (1) and [Zn(L)(Brpbda)]n (2) were prepared by reactions of zinc sulfate heptahydrate with N-donor ligands of 1,4-di(1H-imidazol-4-yl)benzene (L) and auxiliary carboxylic acids of nitroterephthalic acid (H2NO2pbda) and 2,5-dibromoterephthalic acid (H2Brpbda), respectively. The structures of the CPs were characterized by Fourier-Transform Infrared (IR) spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The coordination polymer 1 has two different (4, 4) sql 2D layer structures based on the [Zn(L)(NO2pbda)] moiety, which results in inclined interpenetration with a 2D + 2D → 3D architecture, while the CP 2 exhibits a 3-fold interpenetrating dmp network. The diffuse reflectance spectra are also investigated for the CPs 1 and 2.
