Preparation, 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...
متن کاملPerformance of polyaniline/manganese oxide-MWCNT Nanocomposites as Supercapacitors
Composite electrodes of polyaniline/MnO2-Multi walled carbon nanotube (PANI/MnO2-MWCNT), MnO2-MWCNT nanocomposites and MWCNT was produced by the in situ direct coating approach. The supercapacitor performance of the nanocomposites was studied by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were also investig...
متن کاملAdsorption Mechanism of Lead on Wood/Nano-Manganese Oxide Composite
Discharge of untreated industrial wastewater containing heavy metals such as Pb2+ is hazardous to the environment due to their high toxicity. This study reports on the adsorption, desorption, and kinetic study on Pb2+ removal from aqueous solutions using wood/Nano-manganese oxide composite (WB-NMO). The optimum pH, contact time and temperature for adsorption were found...
متن کاملSynthesis and characterization of manganese oxide and cobalt oxide nano-structure
The preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. The nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from KMnO4 and CoCl2 with respectively source at room-temperature. The structure and surface morphology of the obtained manganese oxide were studied by mea...
متن کاملRemoval of Fe2+ from Aqueous Solution Using Manganese Oxide Coated Zeolite and Iron Oxide Coated Zeolite
The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...
