Surface functionalization of acidified graphene through amidation for enhanced oxygen reduction reaction

Introducing nitrogen atoms is an effective approach to generate graphene-based electrode materials for energy conversion-electrochemical devices. Herein we propose a novel strategy to covalently functionalize the surface of graphene using 4-amino-4H-1,2,4-triazole (AT) and acidified graphene oxide (AGO) to convert the epoxy group to a carboxyl group in the latter to increase the number of amidation sites via a wet chemical method. It has been proven that, compared to graphene oxide (GO), AGO can be covalently functionalized with AT more efficiently due to the selective amidation between the carboxyl and amine groups. Covalent functionalization incorporates nitrogen and creates pores, which increase the number of oxygen reduction reaction (ORR) sites and prevents pi-pi stacking of graphene sheets. The prepared catalyst exhibits superior ORR activity, in terms of current density, electron transfer and stability compared to Pt/C. It has found that the superior ORR performance of the prepared catalyst is due to the higher degree of amidation that leads to the creation of abundant ORR active N-sites at nanoscale level and a porous structure at microscale level, which enhances O-2 mass transportation to the active sites and improve tolerance against methanol during ORR.

Synthesis, physical and photo-electrochemical characterizations of a new hybrid host-guest complex [Cu-12(C2N3H2)(8)Cl][(PW12O40)]

Through careful choice of reduction conductions, a new hybrid host-guest compound [Cu-12(C2N3H2)(8)Cl][(PW12O40)] was synthesized hydrothermally in the presence of 1, 2, 4 triazole as structure-directing agent. The material has been characterized by single-crystal X-ray diffraction, chemical analysis, FT-IR spectroscopy, thermal analysis and UV-Vis diffuse reflectance. The compound based on a two-dimensional (2D) supramolecular porous coordination polymer [Cu-12 (C2N3H2)(8)Cl](3+) can accommodate in its cavities the Keggin polyoxotungstate anions, with host-guest interactions crystallizing in the monoclinic system (Space Group: C2/m). The metal organic species and Keggin anions are connected via hydrogen bonds and Cu center dot center dot center dot O short contacts giving rise to a three-dimensional architecture. The optical study shows a direct transition (1.60 eV) assigned to the O2-: 2p -> Cu+: 4 s transition. The transport properties revealed a semiconductor comportment; the thermal variation of log (conductivity) versus 1000/T was fitted by a least square method to a straight line whose slope gave an activation energy of 54 meV. The chrono-amperometry and photo-electrochemistry, carried out in Na2SO4 (0.5 M) electrolyte, indicate n-type conduction with a flat band potential of +0.10 V-SCE, making [Cu-12(C2N3H2)(8)Cl][(PW12O40)] a promising solar material.

Giant and Reversible Barocaloric Effect in Trinuclear Spin-Crossover Complex Fe-3(bntrz)(6)(tcnset)(6)

A giant barocaloric effect (BCE) in a molecular material Fe-3(bntrz)(6)(tcnset)(6) (FBT) is reported, where bntrz = 4-(benzyl)-1,2,4-triazole and tcnset = 1,1,3,3-tetracyano-2-thioethylepropenide. The crystal structure of FBT contains a trinuclear transition metal complex that undergoes an abrupt spin-state switching between the state in which all three Fe-II centers are in the high-spin (S = 2) electronic configuration and the state in which all of them are in the low-spin (S = 0) configuration. Despite the strongly cooperative nature of the spin transition, it proceeds with a negligible hysteresis and a large volumetric change, suggesting that FBT should be a good candidate for producing a large BCE. Powder X-ray diffraction and calorimetry reveal that the material is highly susceptible to applied pressure, as the transition temperature spans the range from 318 at ambient pressure to 383 K at 2.6 kbar. Despite the large shift in the spin-transition temperature, its nonhysteretic character is maintained under applied pressure. Such behavior leads to a remarkably large and reversible BCE, characterized by an isothermal entropy change of 120 J kg(-1) K-1 and an adiabatic temperature change of 35 K, which are among the highest reversible values reported for any caloric material thus far.

Rheological non-isothermal mechanistic investigation on the curing of glycidyl azide polymer with solid nanofillers

The effects of ammonium perchlorate (AP) and graphene oxide (GO) on the curing of glycidyl azide polymer (GAP) were investigated. The rheological parameters of GAP crosslinked by bispropargyl succinate (BPS) were investigated by rheometry instrument. The curing kinetics by the differential isoconversional method revealed that AP (1 wt%) increased the apparent activation energy from 72.98 to 76.41 kJ mol(-1). However, the presence of GO (0.1 wt%) catalyzed the curing of GAP/triazole by decreasing the apparent activation energy to 62.86 kJ mol(-1). The physical models revealed that the addition of GO changed the cure mechanism of GAP/BPS as it acted as new nucleation sites. The Fourier-transform infrared (FTIR) and X-ray photoelectron (XPS) results also showed that chemical groups on the surface of GO reacted with the hydroxyl groups of GAP, which changed the curing mechanism of GAP/BPS and improved the tension strength of the propellant by 104%.

Efficient copper-catalyzed tandem oxidative iodination and alkyne-azide cycloaddition in the presence of glycine-type ligands

Tandem oxidative iodination and alkyne-azide cycloaddition reaction has provided one of the most widely used methods for preparation of 5-iodo-1,2,3-triazoles. However, stoichiometric copper salts are involved in this type of reaction in order to enhance the reaction effectiveness, which caused some problems related to toxic metal contaminations and less sustainability. In this paper, we described that a copper-catalyzed (10 mol%) tandem oxidative iodination and alkyne-azide cycloaddition could be completed in the presence of the newly-found glycine-type ligands with low-cost Nal as the iodine resource. In the novel reaction system, a wide range of terminal alkyne, organic azide and inexpensive iodide could react effectively in one pot to give structurally diverse 5-iodo-1,4-subsitutied 1,2,3-triazoles. Natural product derivatives and alkynyl pyridines that hardly react under traditional conditions could also be transferred smoothly to the target products for the first time. (C) 2020 Elsevier Ltd.

Vibrational properties of 1D-and 3D polynuclear spin crossover Fe(II) urea-triazoles polymer chains and quantification of intrachain cooperativity

The vibrational dynamics of the iron centres in 1D and 3D spin crossover Fe(II) 4-alkyl-urea triazole chains have been investigated by synchrotron based nuclear inelastic scattering. For the 1D system, the partial density of phonon states has been modelled with density functional theory methods. Furthermore, spin dependent iron ligand distances and vibrational modes were obtained. The previously introduced intramolecular cooperativity parameter H-coop (Rackwitz et al, Phys. Chem. Chem. Phys. 2013, 15, 15450) has been determined to -31 kJ mol(-1) for [Fe(n-Prtrzu)(3)(tosylate)(2)] and to +27 kJ mol(-1) for [Fe(n-Prtrzu)(3)(BF4)(2)]. The change of sign in H-coop is in line with the incomplete and gradual character of the spin transition for the former as well as with the sharp transition for the latter reported previously (Rentschler and von Malotki, Inorg. Chem., Act. 2008, 361, 3646). This effect can be ascribed to the networks of intramolecular interactions in the second coordination sphere of the polymer chains, depending on the spin state of the iron centres. In addition, we observe a decreased coupling and coherence when comparing the system which displays a sharp spin transition to the system with an incomplete soft transition by analyzing molecular modes involving a movement of the iron centres.
