Silver-palladium catalysts for the direct synthesis of hydrogen peroxide.
A series of bimetallic silver-palladium catalysts supported on titania were prepared by wet impregnation and assessed for the direct synthesis of hydrogen peroxide, and its subsequent side reactions. The addition of silver to a palladium catalyst was found to significantly decrease hydrogen peroxide productivity and hydrogenation, but crucially increase the rate of decomposition. The decomposit...

Catalytic Decomposition of Hydrogen Peroxide in the Presence of Synthesized Iron-Manganese oxide Nanocomposites via Different Methods
The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...
متن کاملIsothermal 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 کاملDecomposition of hydrogen peroxide in presence of mixed ligand cobalt (II) and nickel (II) complexes as catalysts
The decomposition of hydrogen peroxide catalyzed by mixed ligand cobalt (II) and nickel (II) complexes as heterogeneous catalysts and adsorbate on alumina has been investigated by measuring the evolution of oxygen at different time intervals between 35-60C. The effect of variation in the concentration of hydrogen peroxide and in the quantity of catalysts on the extent of disproportionation has ...
