A general strategy toward the rational synthesis of metal tungstate nanostructures using plasma electrolytic oxidation method

A general strategy for the rational synthesis of tungstate nanostructure has been developed based on plasma electrolytic oxidation (PEO) technology (up). Using this method, ZnWO4 and NiWO4 nanostructures with controllable morphologies and superior crystallinity can be easily obtained (down), showing obvious advantage in comparison with conventional hydrothermal and sol-gel methods.
