“…For these synthesis methods, in literature, there are a variety of precursors, namely, magnesium nitrate, glycine, Mg(CHCOO) 2 and ethylene glycol, MgCl 2 and NaOH, magnesium foil, toluene and MgCl 2 ⋅6H 2 O, ammonia, polyvinyl alcohol, polyvinyl pyrrolidone, magnesium acetate tetrahydrate, Mg particle, tungsten wire, trioctylphosphine oxide (TOPO) and bis(cyclopentadienyl)magnesium (Cp2Mg), Mg rod electrode, and magnesium acetate, which have been reported for the preparation of MgO nanoparticles. Further, to prepare MgO nanomaterials, various fuels [2][3][4][5][6][7][8][9][10][11][12][13][14][15], namely, glycine, urea, combination of urea, glycine, and cellulose, propane, and 1,3 propane diol, have been used. Among these different fuels, urea [4, 8, 10-12, 14, 15] is 2 Journal of Nanotechnology the most commonly used fuel in the preparation of nano-MgO particles.…”
