摘要:  采用草酸铌和 KOH为原料, 加入少许水研磨至干燥后得到前躯体, 前躯体在5 0 0℃焙烧3h合成了铌酸钾粉末。红外光谱分析结果表明, 在研磨过程中, 原料之间发生了离子交换作用, 有 NH3 被释放出来。以铌酸钾粉末为光催化剂, 在紫外灯照射下, 对亚甲基蓝溶液进行光催化降解实验, 结果表明, 光催化3h后, 亚甲基蓝的降
解率达到9 0%。

Abstract: Potassium Niobate was obtained by grinding the mixture of niobium formate and potassium hydroxide and small amount of water, then dried at room temperature, and finally calcined at 500 ℃ for 3 h . It can be seen from the Infrared spectroscopy that an ionexchange reaction occurred and NH3 was released during grinding. Assynthesized potassium niobate powders were used to degrade methylene blue solution under irradiation of UV, and found that the catalyst showed better photocatalytic properties, and the degradation ratio reaches to 90% after 3 h reaction.

Key words: Potassium niobate, Improved solidstate method, Photocatalysis, Methylene Blue;Lowtemperature synthesis
