2d Nanocrystals Of Zinc And Manganese(II, III) Oxides With Morphology Of Perforated Nanoflakes Obtained Using Hydrolysis Reactions Of Mn(OAc)₂ AND Zn(OAc)₂ By Gaseous Ammonia On The Surface Of Their Aqueous Solutions

Abstract

The paper shows for the first time that 2D ZnO nanocrystals with the structure of wurtzite and Mn3O4 hausmanite and morphology of perforated nanoflakes can be obtained on the basis of compounds that are formed as a result of reactions occurring on the surface of aqueous solutions of acetates of the corresponding metals when it is treated in air atmosphere with gaseous NH3. Application of the marked nanocrystals on the silicon surface makes it hydrophobic in the case of ZnO and superhydrophilic in the case of Mn3O4. Using the proposed synthesis technique, sequential and multiple deposition of these compounds on the substrate surface can be performed and such “multilayers” can exhibit new properties.
