Titanium dioxide quantum dots were prepared and studied as a catalyst for studying the photodegradation of indigo carmine dye in aqueous solution phytotoxicity selected seeds. Tomato seeds (Lycopersicon esculentum) germinated water with different titanium (IV) (TQs) samples (TQ1 TQ2) TiO2 P25 did not observe any influence on germination process. HRTEM, FE-SEM, EDX, XRD used to investigate size, shape, structure created TQs samples. TQ1 TQ2 measured be exactly 2.6 3.4 nm, respectively. The use these methods has demonstrated established that do contain other phases or contaminants. (2.6 nm) (3.4) highly distinguishable BET-specific surface areas 474.0 298.2 m2/g, respectively, effectively at calcination temperatures: 270 320 0C 240 min, by merely employing sol–gel technique. photocatalytic activity was assessed using xenon photoreactor Indigo Carmine commercial model direct sunlight actual industrial wastewater They had distinguishable, strong capabilities, which reached 93 94 %. Also, their rates still discernible until 12 10 repeat times process presence TQ2, an investigation been carried out positive energy consumption ratio (EE/O), done order provide price predictions.
