Intertwined nanopetal assembly of Mg(OH)2 powders

The intertwined nanopetal assembly of Mg(OH)2 powder was synthesized in the present work by a very simple, inexpensive, green chemical route without using any catalysts and templates. The synthesized powder was thoroughly investigated by X-ray diffraction, BET and BJH measurements, Fourier transformed infrared spectroscopy, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, thermo-gravimetric and differential thermal analysis techniques. The results showed that phase pure, oxygen rich Mg(OH)2 powder of 2.7−6.16 nm crystallite size, ~7 nm pore size, and ~93.76 m2 gm−1 surface area was obtained. Finally, the possible growth mechanism of intertwined nanopetal assembly was discussed for the Mg(OH)2 powders.
