摘要
直接采用商品铋酸钠作为光催化剂,研究了不同热处理条件对铋酸钠结构稳定性和光催化活性的影响,考察了铋酸钠对不同有机污染物的光催化降解特性及重复使用性。结果表明,可见光照射下,铋酸钠能够快速降解甲基橙、橙Ⅱ、亚甲基蓝和苯酚,适当热处理能够增强铋酸钠光催化性能,铋酸钠光催化剂性能比较稳定,可以循环利用,具有良好的应用前景。
Using commercial NaBiO3 ·nH2O as photocatalyst, the effects of drying temperature on its structure and photocatalytic activity were investigated. Photocatalytic behaviors and reusability of sodium bismuthate in photocatalytic degradation of different organic pollutants were investigated. The results showed that methyl orange, orange Ⅱ, methylene blue and phenol were degraded effectively by NaBiO3 under visible light irradiation, and the photocatalytic activity was enhanced at appropriate drying temperature. Commercial NaBiO3 · nH2O can be used as a recyclable photocatalyst for degradation of pollutants.
