利用水热法合成了添加不同分散剂的CaTi_2O_4(OH)_2纳米片状结构,讨论了不同分散剂对CaTi_2O_4(OH)_2片状结构光催化性能的影响,通过X射线衍射(XRD)、扫描电镜(SEM)和紫外-可见(UV-Vis)光谱等分析测试技术对产物的微观结构和光学性能进行分析,以罗丹明B为降解对象,研究了添加不同分散剂的CaTi_2O_4(OH)_2对罗丹明B的降解情况。结果表明,添加不同分散剂后产物沿(040)与(251)面取向性生长为片状结构。通过对罗丹明B的降解情况可知,当加入3%的碳酸钠时所制备的CaTi_2O_4(OH)_2的催化活性最高为94.7%。
The CaTi_2O_4 (OH) _2 nanosheets with different dispersants were synthesized by hydrothermal method. The effects of different dispersants on the photocatalytic properties of CaTi_2O_4 (OH) _2 sheet were discussed. The effects of different dispersants on the photocatalytic properties of CaTi_2O_4 (OH) The microstructure and optical properties of the product were analyzed by SEM and UV-Vis spectroscopy. With Rhodamine B as the degradation target, the CaTi_2O_4 (OH) _2 with different dispersants Degradation of rhodamine B The results show that the products grow along the (040) and (251) planes to flaky structures with different dispersants. According to the degradation of rhodamine B, the highest catalytic activity of CaTi 2 O 4 (OH) 2 was 94.7% when adding 3% sodium carbonate.
