In this research, various concentrations of potassium permanganate were dissolved in water, and manganese acetate
and calcium acetate were added to it in alkaline media.
Zinc acetate (Zn[(ac).sub.2] x 2[H.sub.2]O) and manganese acetate (Mn[(ac).sub.2] x 4[H.sub.2]O) act as precursors and absolute ethanol was used as a solvent to synthesis Mn-doped ZnO nanoparticles.
The chemicals used were zinc acetate dehydrate (Zn[(OAc).sub.2]-2[H.sub.2]O), >99.5%, from Fluka), manganese acetate tetrahydrate, (Mn[(OAc).sub.2]-4[H.sub.2]O, >98%), sodium hydroxide (NaOH, 98%), and absolute ethanol ([C.sub.2][H.sub.5]OH, >99%).
The second solution consisted of 1.0 mM of manganese acetate tetrahydrate (Mn(ac)2-4[H.sub.2]O) in 10 mL of ethanol.
One such macromolecule is manganese acetate
, which includes a cluster of 12 manganese ions and 16 acetate ions.
Manganese nitrate (50% Mn[(N[O.sub.3])].sub.2] in water), manganese chloride (Mn[Cl.sub.2]), manganese sulfate monohydrate (MnS[O.sub.4] x [H.sub.2]O), manganese acetate
tetrahydrate (Mn[C.sub.4][H.sub.6][O.sub.4] x 4[H.sub.2]O), and tetraethyl orthosilicate ([C.sub.8][H.sub.2]0[O.sub.4]Si) were obtained from Aladdin Chemistry Co.
In the method of synthesis in emulsion medium, some quantities of saturated solution of manganese acetate
together with the desired oil (peanut oil, olive oil or paraffin) were exposed to ultrasonic waves for a definite time, then precipitations were removed and dried in oven.
We find that a nanoworm morphology can be obtained from manganese acetate
upon oxidation as shown in Figure 2(a).
Monodisperse MnO nanocrystals have been synthesized by thermal decomposition of manganese oleate using the hot-injection method or thermal decomposition of manganese acetate
in the presence of oleic acid [51, 52].
