The isothermal decomposition of a CL-20/HMX co-crystal explosive

Abstract: The isothermal decomposition process of CL-20/HMX co-crystals was studied through an isothermal decomposition dynamics research method. The pressure versus time curves of the gas generated by the CL-20/HMX co-crystal thermal decomposition present a significant inflection point at the decomposition extent of 70%. Furthermore, the residue of the CL-20/HMX co-crystals was investigated by HPLC and FTIR spectroscopy to understand the decomposition process. The results manifest that the decomposition of the CL-20/HMX co-crystals before and after the inflection point conforms to different model equations with the activation energies of 149.3 kJ mol−1 and 169.0 kJ mol−1, respectively. The thermal decomposition of the CL-20/HMX co-crystals is a coupling process. Clearly, the decomposition rate of CL-20 is much higher than that of HMX before the inflection point; CL-20 is almost consumed when the inflection point is reached in the pressure–time curve of the CL-20/HMX co-crystal thermal decomposition and then, HMX accelerates the thermal decomposition of the CL-20/HMX co-crystals.

A novel metal-organic framework precursor strategy to fabricate sub-micron CuO microspheres for catalytic thermal decomposition of ammonium perchlorate

Abstract: A novel metal-organic framework (MOF) precursor strategy to fabricate CuO microspheres via air-flow impacting (AFI) synthetic method was reprted in the work. The MOF precursor HKUST-1 and its derived CuO microspheres were characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, the catalytic activity of CuO microspheres on the thermal decomposition of ammonium perchlorate (AP) was investigated by differential thermal analysis (DTA). The results of DTA indicated that the addition of CuO microspheres to AP observably reduces the decomposition temperature due to its high contact area and much catalytic active sites. The HKUST-1 derived CuO microspheres are expected to remarkably improve the catalytic performance in AP-based composite solid rocket propellants.

Recent advances in metal-organic frameworks/membranes for adsorption and removal of metal ions

Abstract: Metal-organic frameworks (MOFs) have attracted extensive research interest because of their high specific surface area, tunable microporosity, low skeleton density and good stability, and they are seen as ideal functional materials for the detection and removal of metal ions. Current research is mainly focused on the trade-off between the permeability and selectivity, and the development of MOFs composites with superior performance to obtain satisfactory adsorption and separation capacity, such as MOFs membranes. In this review, we first summarize the various design and synthesis strategies for MOFs and MOF membrane materials, including with/without solvent, the mechanochemical method, the primary growth method and the secondary growth method. The recent advances in MOFs and MOFs membranes for the adsorption and removal of different types of metal ions are then highlighted. Finally, the opportunities and challenges for the future development of MOFs and MOFs membranes are proposed. This review aims to provide a deep understanding of the rational design and application research of MOFs and MOF membranes and promote development and progress in MOF hybrid materials.
