Synthesis of single-crystal beta-Ni(OH)(2) nanodisks and alpha-Fe2O3 nanocrystals in C2H5OH-NaOH-NH3 center dot H2O system
Circular beta-Ni(OH)(2) nanadisks and rhombohedral and hexagonal alpha-Fe2O3 nanocrystals were prepared using the C2H5OH-NaOH-NH3 center dot H2O system under hydrothermal conditions. The C2H5OH/H2O solvent is an appropriate one for the growth of these two materials with their thermodynamically favored morphologies. The possible formation mechanisms are discussed.
