Abstract

A solvothermal route to MnWO₄ nanoparticles and nanorods has been developed. These nano-size products have been characterized by X-ray diffraction and transmission electron microscopy. The pressure, pH and temperature of the reaction systems were found to play important roles in determining the morphologies of the MnWO₄ nanocrystalline products. Homologous surfactants have also been used to control the formation of MnWO₄ nanocrystals. These surfactants were found to play a crucial role in the solvothermal route, and there is apparently a relationship between the molecular weight of the added homologous surfactants and the aspect ratio of the resulting nanorods.
