| Abstract: | The tungsten acid was obtained via acidification of sodium tungstate. Then the tungsten oxide alien nano-powder was synthesized by hydrothermal method. The influences of sulfate, reaction time and molybdenum on morphology were investigated.The field emission scanning electron microscopy（FE-SEM）and energy dispersive X-ray spectrometer （EDX）were used to characterize the products.The possible formation mechanism was researched based on the experimental results. |
