According to X-ray analysis, the samples with different phase ratio of anatase: rutile were obtained. The structural and morphological characteristics of TiO2 were carried out. A batch microreactor for photocatalytic reactions monitoring has been constructed. For the first time, the rate of photocatalytic degradation of Rhodamine B was assessed using a smartphone in the presence of P25 photocatalyst and H2O2. Hydrogen peroxide has been shown to accelerate the dye photodegradation. However, the accelerating effect decreases at high concentrations of H2O2, because the formed hydroxyl radicals react with an excess of H2O2 molecules. The photocatalytic activity of peroxotitanate TiO2 was studied on model aqueous solutions of Direct Red 23, Direct Red 81, Congo red, Methyl orange and Rhodamine B.
