Abstract

Dyes as one of the majority critical environmental pollutants from industrial wastewaters, have caused many concerns for researchers. In this research an effective photocatalyst based on La₂O3-SiO₂ nanocomposite was prepared and evaluated for degradation of toluidine blue (TB) dye. The prepared photocatalyst was illustrated impressive performance in degradation of TB equal to 97% by visible light irritation. Accuracy of synthesized nanocomposite was studied by some technics including FE-SEM, FT-IR, EDX and mapping analysis. Also the effective parameters in degradation percent of TB such as pH, temperature, time, concentration and the amount of nanocomposite were investigated and optimized equal to amounts of 8.0, 25℃, 80 min, 3.0 µg/mL and 0.04 mg respectively.

制备 La2O3-SiO2 纳米复合材料并研究其降解甲苯胺蓝染料的光催化性能

摘要染料作为工业废水中最重要的环境污染物之一，引起了研究人员的广泛关注。本研究制备了一种基于 La2O3-SiO2 纳米复合材料的有效光催化剂，并对其降解甲苯胺蓝（TB）染料的效果进行了评估。在可见光的刺激下，所制备的光催化剂对甲苯胺蓝染料的降解率高达 97%，表现令人印象深刻。通过一些技术，包括 FE-SEM、FT-IR、EDX 和制图分析，研究了合成纳米复合材料的准确性。此外，还研究了影响 TB 降解率的有效参数，如 pH 值、温度、时间、浓度和纳米复合材料的用量，并分别优化为 8.0、25℃、80 分钟、3.0 µg/mL 和 0.04 mg。
