The study evaluates the azo dye degradation potential of nano-TiO₂; its composites with low-cost substrates in the form of powder and encapsulated bead for two widely used azo dyes, methyl orange (MO) and congo red (CR) under solar and ultraviolet (UV) irradiation. Degradation potential varied according to the dye concentration, chemistry of dye, light source, and the formulation of the photocatalyst. Both the dyes were completely decolorized at 100 mg/L concentration and to some extent at 1,000 mg/L concentration. The activated charcoal-titanium dioxide (AC-TiO₂) nanocomposite in the presence of solar radiations proved to be an economic and efficient substrate for degradation of the test dyes exhibiting combined action of adsorption and photocatalytic phenomena.

用于修复纺织染料的低成本纳米 TiO2 复合材料：评价太阳和紫外线照射的影响

该研究评估了纳米TiO ₂对偶氮染料的降解潜力；在太阳光和紫外线 (UV) 照射下，它与两种广泛使用的偶氮染料甲基橙 (MO) 和刚果红 (CR) 的粉末和封装珠粒形式的低成本基材复合。降解潜力因染料浓度、染料化学性质、光源和光催化剂的配方而异。两种染料在 100 mg/L 浓度和 1,000 mg/L 浓度时都完全脱色。在太阳辐射的存在下，活性炭-二氧化钛（AC-TiO ₂）纳米复合材料被证明是一种经济有效的基材，用于降解表现出吸附和光催化现象的联合作用的测试染料。
