Benzyl alcohol and transition metal chlorides as a versatile reaction system for the nonaqueous and low-temperature synthesis of crystalline nano-objects with controlled dimensionality.
The reaction of transition metal chlorides with benzyl alcohol leads at low temperatures to oxidic nanostructures with low-dimensional particle shapes such as nearly spherical titania anatase nanoparticles, vanadium oxide nanorods, and tungsten oxide nanoplatelets. The process is simple, allows a scale-up in gram quantities, and leads to highly crystalline materials. Ethanol solutions containing tungsten oxide nanoparticles exhibit blue luminescence upon UV irradiation at room temperature.
