文摘

The microwave synthesis of MnC₂O₄¡¤2H₂O nanoparticles was performed through the thermal double decomposition of oxalic acid dihydrate (C₂H₂O₄¡¤2H₂O) and Mn(OAc)₂¡¤4H2O solutions using a CATA-2R microwave reactor. Structural characterization was performed using X-ray diffraction (XRD), particle size and shape were analyzed using transmission electron microscopy (TEM). The chemical in the structures was investigated using electron paramagnetic resonance (EPR) as well as optical absorption spectra and near-infrared (NIR) spectroscopies. The nanocrystals produced with this method were pure and had a distorted rhombic octahedral structure.
