Preparation, Characterization and Surface Area Properties of Manganese Oxide Nanoparticles
Main Article Content
The precipitation method was used to prepare manganese oxide nanoparticles (MnO2NPs) successfully. Infrared spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), X-ray dispersion spectroscopy and (EDS) X-ray Diffraction (XRD) were used to characterize the microstructure, morphology and particle size of particles that produced by this method. The N2 adsorption-desorption isotherms, pore structure and specific surface area of MnONPs were measured by using Langmuir, Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) academic models. The results show that the sample has a tetragonal crystal structure with an average particle size of about 35 nm as determined by SEM and verified by XRD. So, the specific surface area is 57.449 m2g-1, pore volumes are 0.2454 cm3g-1 and average pore diameter is 6.95 nm.
