Isothermal decomposition of hydrogen peroxide dihydrate.
We present a new method of growing pure solid hydrogen peroxide in an ultra high vacuum environment and apply it to determine thermal stability of the dihydrate compound that forms when water and hydrogen peroxide are mixed at low temperatures. Using infrared spectroscopy and thermogravimetric analysis, we quantified the isothermal decomposition of the metastable dihydrate at 151.6 K. This deco...
متن کاملUnusual hydrogen peroxide decomposition on stoichiometric insulating oxide ultrathin films
The hydrogen peroxide dissociation on MgO(001) films deposited on Mo(001) surface is investigated by employing periodic density-functional theory methods. The pristine MgO(001) surface showing chemical inertness prefers the weak adsorbing molecular configuration and is extremely difficult to react with hydrogen peroxide. As far as we know, energetically favorable decomposition state of hydrogen...
متن کاملTheoretical Study on the Urea-Hydrogen Peroxide 1:1 Complexes
The structures, interaction energies, vibrational analysis, and electronic properties for different urea-hydrogen peroxide (UHP) 1:1 complexes have been studied. Density functional theory (DFT) using the B3LYP hybrid exchange-correlation functional was employed to characterize five new cyclic structures in addition to the experimental one. The basis sets used were Dunning’s correlation consiste...
متن کاملDecomposition of hydrogen peroxide in a catalytic fluidized-bed reactor
The decomposition of H2O2 by a novel supported g-FeOOH catalyst was performed in a continuous fluidized-bed reactor. This catalyst has been successfully used in the treatment of organic contaminants with H2O2 in our previous work. In this study, we attempted to determine the effects of pH, H2O2 concentration, and catalyst concentration on the decomposition of H2O2. An approach, we regarded this...
متن کاملControlling Non-Catalytic Decomposition of High Concentration Hydrogen Peroxide
Hydrogen peroxide (H2O2) is a strong oxidizing agent. High concentration H2O2 or High Test Peroxide (HTP) has been used extensively in the past in propulsion applications as mono and bipropellant. At low temperature, HTP can be catalytically decomposed to water and oxygen. Drawbacks to this approach include catalyst poisoning due to the presence of stabilizers in HTP, and susceptibility of the ...
