Description
Summary:•We have synthesised magnesium oxalate nanorods.•The materials were characterized by XRD, TEM, NIR and optical absorption.•The synthesized nano rod is 80nm in diameter and 549nm in length. Synthesis of MgC2O4⋅2H2O nano particles was carried out by thermal double decomposition of solutions of oxalic acid dihydrate (C2H2O4⋅2H2O) and Mg(OAc)2⋅4H2O employing CATA-2R microwave reactor. Structural elucidation was carried out by employing X-ray diffraction (XRD), particle size and shape were studied by transmission electron microscopy (TEM) and nature of bonding was investigated by optical absorption and near-infrared (NIR) spectral studies. The powder resulting from this method is pure and possesses distorted rhombic octahedral structure. The synthesized nano rod is 80nm in diameter and 549nm in length.
