A family of <italic>cyclo</italic>-pentazolate anion-based energetic salts was designed and synthesized by a rapid method, these were evaluated as potential next generation materials.
Abstract According to previous reports, metal cations or water molecules are necessary for the stabilization of pentazolate anion ( cyclo ‐N 5 − ) at ambient temperature and pressure. Seeking a new method stabilize N is big challenge. In this work, three anhydrous, metal‐free energetic salts based on 3,9‐diamino‐6,7‐dihydro‐5 H ‐bis([1,2,4]triazolo)[4,3‐ e :3′,4′‐ g ][1,2,4,5] tetrazepine‐2,10‐diium, ‐carbamoylguanidinium, oxalohydrazinium (oxahy + were synthesized isolated. All...
Hierarchical structure plays an important part in the performance of supercapacitor materials. Herein, Ni/Co hybrid MOFs with hierarchical sphere were synthesized controllably using hydrothermal method. With controlling molar ratio and ligand, morphology evolution optimized electrochemical carefully studied. As a battery-type electrode material, MOF (Ni/Co-1:2) delivered high specific capacity 339.3 C·g−1 at current density 1 A·g−1 good cycling 70.3% retention after 2000 cycles its direct...
A green and gram-scale strategy has been developed for the synthesis of Fe single atom/N,S-doped carbon catalyst via pyrolysis polyaniline-modified Fe,S-doped ZIFs, in which ZIFs can be prepared water at room temperature.
From a 1D sodium-N5- framework, new zeolite-like metal-organic framework (MOF) with fascinating 3D structure was successfully constructed. It exhibited an enhanced thermal stability decomposition temperature (onset) of 129 °C and coordination ability (five-coordination) cyclo-N5- in weak alkaline conditions. The MOF bulky size offers opportunities not only for the formation porous materials but also to control balance between performance polynitrogen materials.
A carbon-free inorganic-metal complex [Zn(H2O)4(N5)2]·4H2O was synthesized by the ion metathesis of [Na(H2O)(N5)]·2H2O solution with Zn(NO3)2·6H2O. The well characterized IR and Raman spectroscopy, elemental analysis (EA), powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC). structure confirmed single-crystal crystallography a Zn(ii) is coordinated in quadrilateral bipyramid environment which axial position formed two nitrogen atoms (N1) from pentazolate rings...

Abstract Pentazolate anion ( cyclo ‐N 5 − ), and/or N 3 , NO were used as the ligands to obtain a series of nitrogen‐rich energetic three‐dimensional (3D) frameworks [Cu(N )(N )] n [Ag(N [Ba(N )(NO )(H 2 O) ] and [NaBa (N ) 6 (NO by self‐assembly. These characterized single‐crystal X‐ray diffraction, SEM, IR Raman spectroscopy, elemental analysis, thermal analysis. All exhibited regular supramolecular structures excellent stabilities at room temperature which can be attributed strong...
Energetic metal–organic frameworks (EMOFs) with a high oxygen content are currently hot spot in the field of energetic materials research. In this article, two series EMOFs different ligands were obtained by reacting 1-(trinitromethyl)-1H-1,2,4-triazole-3-carboxylic acid (tntrza) metal iodide and nitrate, respectively. Furthermore, their structure, thermal stability, decomposition kinetics, energy performance fully characterized. The research results revealed that synthesized possess wide...
Nickel–cobalt layered double hydroxides (NiCo-LDHs) have been widely used as supercapacitor materials, and their performance can also be improved by doping engineering. However, the systematic study of halogen anion (X–)-modified NiCo-LDH has rarely reported. In this study, X– were to modify nickel–cobalt carbonate (NiCo-CHs) via hydrothermal preparation. The resulted in changes morphology NiCo-CH. particular, electronegativity electron-withdrawing ability found key metal valence NiCo-CHs....
It is a hot debate on the Meso-Cenozoic dynamics of East Asian continental margins,since nature,type and evolution its margins are not well-known..This paper systematically summarizes results plate reconstructions margin since Permian over past 40 years with emphasis new research in 10 years.The mainly focuses variation types Late Triassic,the transitions among different tectonic domains.Our data suggests that as whole experienced pre-Triassic passive margin,a Triassic-Early Cretaceous...
