Abstract Ceramic TiO2 nanocomposites were manufactured using the mechanical grinding and annealing procedure with the powder mixtures of fly ash, waste glass powder and nano-TiO2. The chemical durability of the heat-treated specimens was examined at 850 °C with nano-TiO2 contents to evaluate the morphological properties with/without the acid treatment, and the photocatalytic activity for bisphenol A, acetaldehyde, 2,4-dichlorophenoxyacetic acid, methylene blue, and methyl orange was investigated. The compressive strength, bending strength, and Vickers hardness of the specimens were also analyzed. Ceramics nanocomposite with 15.0 wt% TiO2 was found to be the optimum photocatalyst mechanism in all cases with/without the acid treatment.

酸处理陶瓷TiO 2 纳米复合材料的化学耐久性和光催化活性

摘要 采用粉煤灰、废玻璃粉和纳米TiO2 的混合粉末,采用机械研磨和退火工艺制备了陶瓷TiO2 纳米复合材料。在 850 °C 下用纳米 TiO2 含量检查热处理样品的化学耐久性,以评估酸处理后的形态特性,以及对双酚 A、乙醛、2,4-二氯苯氧乙酸、亚甲基的光催化活性蓝色和甲基橙进行了研究。还分析了试样的抗压强度、弯曲强度和维氏硬度。发现含有 15.0 wt% TiO2 的陶瓷纳米复合材料在酸处理/不酸处理的所有情况下都是最佳的光催化机理。
