Manganese oxides are one of the most important groups of materials in energy storage science. In order to fully leverage their application potential, precise control of their properties such as particle size, surface area and Mn (x) (+) oxidation state is required. Here, Mn3O4 and Mn5O8 nanoparticles as well as mesoporous α-Mn2O3 particles were synthesized by calcination of Mn(II) glycolate nan...

Widening the use of renewable sources requires more efficient energy storage systems to overcome inherent intermittence solar energy. In this respect, thermal coupled concentrated power represents an inexpensive technology achieve that goal. particular, reversible thermochemical reactions is promising due a higher density if compared with commercial sensible heat on molten salts. However, some ...

Hybrid nanomaterials based on manganese, cobalt, and lanthanum oxides of different morphology phase compositions were prepared using a facile single-step ultrasonic spray pyrolysis (USP) process tested as electrocatalysts for oxygen reduction reaction (ORR). The structural morphological characterizations completed by XRD SEM-EDS. Electrochemical performance was characterized cyclic voltammetry ...

Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...

Thin films of physical mixture Hausmannite Mn3O4 and lithium (Li) are synthesized by spray pyrolysis technique. Structural, morphological, optical, electrical, wettability, photocatalytic properties have been investigated. X-ray diffraction (XRD) Raman spectra, Scanning electron microscope (SEM) images, electrical measurements show that Li nanoparticles formed both on top surface the film insid...
