摘要 通过结合固相反应与水热法制得一种新型的光催化剂Na2Ta2O6,并对其进行了XRD、SEM表征。由紫外可见漫反射光谱推测其禁带宽度约为4.6 eV,并对其在紫外光区下光催化降解碱性藏花红溶液的行为进行了研究。发现其具有好的结晶性、特殊的棒状结构以及较好的光催化活性。 A novel photocatalyst, Na2Ta2O6 was prepared by a combined solid -state reaction and hydrothermal approach. The sam pies were characterized by powder X - ray diffraction （XRD）. The morphology and particle size of the product were analyzed by scanning electron microscope. The band gap of the Na2Ta2O6 was about 4. 6eV based on UV - vis diffuse reflectance spectroscopy. Also, it showed good crystallinity, special structure and higher photocatalytic activity even without cocatalysts under UV - light irradiation by model experiment of degradation of the solution of Safranine T.
