Glycerol-controlled synthesis of a series of cobalt acid composites and their catalytic decomposition toward several energetic materials

Abstract

One of the challenges in solid propellant formulation is the ability to extend the combustion performance by efficiently catalyzing the decomposition of energetic additives. Herein, series of cobalt acid composites...

Correlation of Efficient Dispersion and Catalytic Performance of Nanocombustion Catalysts in Energetic Materials: A Case Study of the Nanocopper Oxide Catalyst with Superfine Ammonium Perchlorate

“…However, the use of nanocatalytic materials in energetic materials also suffers from a serious problem, that is, the strong agglomeration phenomenon of nanocatalytic materials seriously restricts their excellent catalytic properties. Nowadays, various methods have been adopted to suppress the agglomeration phenomenon of nanocatalytic materials, such as the preparation of uniformly dispersed nanoparticles by sol–gel and solvothermal methods, improving the dispersion of nanoparticles in the form of loading, etc. − …”

The positive correlation between the dispersion and catalytic performance of Fe2O3 nanoparticles in nano-Fe2O3–ultrafine AP energetic composites supported by solid UV-vis spectroscopy

“…For example, techniques, such as the sol-gel method and solvothermal method, are used to improve the dispersity of nanocatalytic materials through their preparation method; moreover, the dispersity could be improved by loading. [27][28][29][30][31] However, the dispersity of nanomaterials cannot be evaluated. Techniques, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and specific surface area testing (Brunauer-Emmett-Teller method), can only analyze the relative dispersity of the samples and cannot quantitatively analyze the dispersity of nanomaterials.…”
