Synthesis of Manganese Oxide Microspheres by Ultrasonic Spray Pyrolysis and Their Application as Supercapacitors
Manganese oxide (MnO 2 ) microspheres are prepared using an ultrasonic spray pyrolysis (USP) process. A mixed solution of potassium permanganate and hydrochloric acid is nebulized into microsized droplets, which are then carried by air fl ow through a furnace tube. Each microdroplet serves as one microreactor and produces one microsphere. Upon heating, KMnO 4 is decomposed into MnO 2 microspher...
متن کاملStructural, Optical Investigation of Manganese Oxide Thin Films by Spray Pyrolysis Technique
Thin films of MnO2 are well suited for Electrochromic Photo-Voltaic (ECPV) effect and superconducting phenomenon (such as solar cells) due to its electrical and optical properties. MnO2 thin films were prepared on glass substrate using a simple and low-cost chemical spray pyrolysis technique at different substrate temperature. The MnO2 films were characterized by X-ray diffraction (XRD), transm...
متن کاملBiomimetic morphological design for manganese oxide and cobalt hydroxide nanoflakes with a mosaic interior{{
We synthesized manganese oxide and cobalt hydroxide nanoflakes with mosaic interiors in aqueous solutions containing poly(acrylic acid) and poly(ethyleneimine), respectively. Nanocrystals 2–3 nm in size made up the mosaic interiors and oriented architectures in the flakes less than 100 nm in width and 10 nm in thickness. The organic polymers coordinated to the metal ionic species and interacted...
متن کاملElectrode reactions of iron oxide-hydroxide colloids.
Small-sized FeO(OH) colloids stabilised by sugars, commercially available for the clinical treatment of iron deficiency, show two waves during cathodic polarographic sweeps, or two current maxima with stationary electrodes, in neutral to slightly alkaline aqueous medium. Similar signals are observed with Fe(III) in alkaline media, pH > 12, containing citrate in excess. Voltammetric and polarogr...
متن کاملPreparation, Characterization and Antibacterial Activity of Manganese Oxide Nanoparticles
Manganese oxide nanoparticles (Mn3O4-NPs) were prepared using precipitation method. The prepared nanoparticles were characterized by a number of techniques, including X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transforms infra red (FT-IR) spectroscopy. The XRD pattern showed that the structure of...
