Abstract

Abstract : A new Ag(i )-based HE-MOFs exhibited a compact 3D structure with channels containing coordinated NO3 − and CH3 COO − ions. The superior density, thermostability, insensitiveness and detonation properties indicated it can be used as potential explosive. Abstract : A new Ag(i )-based HE-MOFs, [Ag3 (H2 ZTO)3 (NO3 )2 (CH3 COO)] n (1, H2 ZTO = 4, 4′-azo-1, 2, 4-triazol-5-one), was successfully synthesized, which exhibited a compact 3D structure with channels incorporating coordinated NO3 − and CH3 COO − ions. Based on TG and DSC analyses results, a superior thermostability and rapidly thermal decomposition process exist in1 . The non-isothermal kinetic for exothermic process of1 is studied by Kissinger's and Ozawa's methods. The sensitivity tests and calculated detonation properties show that1 can be used as a potential explosive. By comparing1 with the previously reported HE-MOFsatrz-1 andatrz-2, a revelation for regulating the heat of detonation of 3D HE-MOFs based on the coordinated moieties in channels has been found. In addition, 1 was explored as a combustion promoter to accelerate the thermal decomposition of RDX (1, 3, 5-trinitro-1, 3, 5-triazinane) by differential scanning calorimetry.
