Retraction: Catalytic decomposition of ammonium dinitramide (ADN) as high energetic material over CuO-based catalysts

مطالعه اثر کاتالیستی اکسید روی )ІІ( (ZnO) با مورفولوژی متفاوت بر تجزیه حرارتی آمونیوم دی نیترآمید (ADN)

Ammonium dinitramide (ADN) with a positive oxygen balance (25.8%) is a metal free- energetic compound, which is used in military explosives and smokeless or green solid propellants. Combustion products of solid propellants based on ADN are clean and smokeless and they do not release hydrogen chloride gas, which can be an excellent alternative compound as an oxidizer in the solid propellant form...

Catalytic Decomposition of Ammonia over Bimetallic CuO/CeO2 Nanoparticle Catalyst

The oxidation of ammonia to nitrogen by selective catalytic oxidation (NH3-SCO) over a bimetallic CuO/CeO2 nanoparticle catalyst at temperatures between 423 and 673K. A bimetallic CuO/CeO2 nanoparticle catalyst was prepared by co-precipitation method at molar ratio of 6:4. This study also considers how the concentration of influent NH3 (C0 = 800 ppm), the space velocity (GHSV = 92000/hr), the r...

Synthesis of Ammonium Dinitramide by Nitration of Potassium and Ammonium Sulfamate. The Effect of Sulfamate Conterion on ADN Purity

Nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °C. The reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). The difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. It was found that both the yield and purity of the product is better starting with potassium ...

CO x Free Hydrogen Production by Catalytic Decomposition of Methane Over Porous Ni/Al2O3 Catalysts

Mechanism and kinetics for ammonium dinitramide (ADN) sublimation: a first-principles study.

The mechanism for sublimation of NH(4)N(NO(2))(2) (ADN) has been investigated quantum-mechanically with generalized gradient approximation plane-wave density functional theory calculations; the solid surface is represented by a slab model and the periodic boundary conditions are applied. The calculated lattice constants for the bulk ADN, which were found to consist of NH(4)(+)[ON(O)NNO(2)](-) u...
