采用简单的溶剂热法制备了非化学计量比的氧化钨纳米棒，其长度可达几微米，直径为5-20 nm。结果表明，所制备的氧化钨纳米棒在可见光照射下具有良好的光催化性能。在光照2.5 h的条件下，氧化钨纳米棒对甲基橙子溶液的降解率高达98%。水热法制备的纳米棒具有优异的可见光催化性能，这可能是由于其独特的结构、优异的光吸收特性和高的比表面积。
Non-stoichiometric tungsten oxide nanorods with length up to few microns and diameters of 5-20 nm were initially prepared using a simple solvothermal method. The as-synthesized tungsten oxide nanorods were found to exhibit excellent photocatalytic properties under visible light irradiation. The degradation ratio of the methyl orange solutions by the tungsten oxide nanorods was as high as 98% under irradiation for 2.5 h. The excellent visible-light-driven photocatalytic properties of the hydrothermally-prepared nanorods may be due to a combination of their unique structure, outstanding light adsorption feature and high specific surface area.
