Highly porous homoleptic Ni(bpb) and Zn(bpb) materials have been obtained by reaction of nickel(II) zinc(II) salts with the deprotonated form 1,4-(4-bispyrazolyl)benzene ligand (H2bpb). Ab-initio structure solution methods thermodiffractometry allowed determination their crystal structures, framework flexibility, thermal stability. The different stereochemical requirements Ni(II) Zn(II) ions induce, in Zn(bpb), rhombic square channels, respectively, accounting for 57 65% total cell volume....
The continuous and dramatic increase of global demand for energy resources makes it urgent to develop affordable nanostructured materials act as efficient electrocatalysts (ECs) in the energy-related reactions. Metal–organic framework (MOF) template pyrolysis production carbon-based is a very promising methodology produce ECs. Herein, we report preparation, characterization (XPS, CHNS analysis, ICP-OES, XRD, TEM, SEM/EDS), application oxygen evolution reaction (OER) reduction (ORR) ECs...
The selective functionalization of carbon nanotube surfaces is crucial for many potential applications these materials. For this purpose several oxidants, among other substances, are used. aim to reach a large degree which depends on the oxidant character reagent. reason multiwall nanotubes (MWCNTs) by treatment with ozone in basic solution studied. At pHs, results into hydroxyl radicals whose reduction very high (E° = 3.06 V). have been compared those obtained gas phase and cold oxygen...
This paper deals with the modifications of chemical surface functionalities and textural changes a glassy carbon produced by three oxidizing agents: ozone, hydrogen peroxide, oxygen plasma. The are evaluated using Fourier transform infrared spectroscopy, temperature-programmed desorption−mass spectrometry, titrations Boehm method. studied mercury porosimetry N2 CO2 adsorption at 77 273 K, respectively. Ozone is more effective agent than H2O2 It able to introduce much larger amounts on other...
The novel coordination polymers [Cu(Hoxonic)(H(2)O)](n) (1) and [Cu(Hoxonic)(bpy)(0.5)](n)1.5 n H(2)O (2 subsetH(2)O) (H(3)oxonic: 4,6-dihydroxy-1,3,5-triazine-2-carboxylic acid; bpy: 4,4'-bipyridine) have been isolated structurally characterised by ab initio X-ray powder diffraction. dense phase 1 contains 1D zig-zag chains in which Hoxonic dianions bridge square-pyramidal copper(II) ions, apically coordinated water molecules. On the contrary, 2 subsetH(2)O, prepared solution solventless...
Tuning the conducting and photoluminescence properties of molecules comprising silver(<sc>i</sc>)–cytosine base pairs.
This article reports a new way to covalently bond chlorine multiwalled carbon nanotubes (MWCNTs) by using tetrachloride cold plasma treatment. Several factors controlling the efficiency of treatment were considered. In particular, methodology produce and temperature time taken into account. The largest surface concentration was obtained when MWCNTs treated with helium before CCl4 activate surface. Short periods (5–10 min) then sufficient reach high degrees chlorination (up 19.2% weight) much...
Controlling graphene conductivity is crucial for its potential applications. With this focus, paper shows the effect of non-covalent bonding a pyrimidine derivative (HIS) on electronic properties (G). Several G-HIS hybrids are prepared through mild treatments keeping unaltered structures both G and HIS. The attachment HIS to occurs by π–π stacking HIS-aromatic residue with surface. This partially blocks pz electrons G, giving rise splitting valence conduction bands. Moreover, width directly...
The pyrolysis of bisphenol A polycarbonate (PC) can be a solution to chemical recycling this widely used polymer, which, once it is used, losses its value. char residue produced in the constitutes more than quarter weight PC pyrolyzed and considered one drawbacks process. hypothesis that such become potential good precursor for selective carbon adsorbents, attending high content regular structure worth considering. Therefore, work analyses physical activation produce high-capacity adsorbents...
