Tungsten trioxide (WO 3) nanoplates have been synthesized successfully by a simple reaction of tungsten powder and water without any organics at 300 o C. The formation of nanoplates by the reaction of metals with water is suggested to occur due of decomposition of water by the metal giving hydrogen. The nanoplates are having an average thickness of 150nm and an average width of 400nm. A feasible mechanism for the formation of nanoplates has been discussed in view of the experimental results.

Moreover, the technique does not require any sophisticated equipments and as such can be extended and expanded to other oxides. To our knowledge, the technique has not been reported in the literature earlier.
