Precipitate Composition

Mn-Mo-O catalysts with a different Mo/Mn ratio have been prepared by precipitation. The precipitate composition as a function of solution concentration and pH was studied by X-ray, IR, thermal and chemical methods. Formation of manganese molybdates with MnMoO4.1.5H2O, Mn3Mo3O12.2.5H2O, and Mn3Mo4O15.4H2O composition has been supposed. It is concluded that pure MnMoO4 may be obtained in both acid and alkaline media, the pH values depending on the concentration of the initial solutions. The maximum Mo/Mn ratio in the precipitates is 1.33. The formation of pure Mn3Mo4O15.4H2O is possible in weakly acidic media. This process is favoured by increasing the concentration of initial solutions.

Core Shell Nanoparticles

A facile one pot synthesis and in situ electrodeposition of Au–Pd core–shell nanoparticles (Au@Pd NPs) could be achieved in a deep eutectic solvent. The fabricated Au@Pd NPs modified graphite showed superior electrocatalytic properties for methanol oxidation at low activation energies.
