Journal Article 2024 03 01 Magnesium hydroxide Mg(OH)2 nanorods with diameters of 90±10nm and lengths of more than 2μms were prepared by a simple route at ~75oC in ambient air. The approach is based on reaction of magnesium powder and de-ionized water without the use of any harmful, toxic or corrosive reagents. Characterization using X-ray diffraction (XRD) shows single crystalline structure of Mg(OH)2 (brucite) whereas Scanning Electron Microscopy (SEM) showed that nanorods are almost uniform in size. Since only water is used as a solvent as well as a source of oxygen, we believe that this manufacturing process is suitable for mass production of nanostructures safely.
