The article considers the photochemical dissociation of the phenol
solution in the presence of TiO₂ nanoparticles, which synthesized in
moderate conditions and dimensions vary between 10-30 nm and the 100mg/ml NH₃
solution. The appearance of photochemical dissociation was confirmed on
the basis of the absorption curves taken before and after the process and Abs
curves were drawn on the “Varian” device. Phenol's photochemical dissociation in UV-visible area
has been confirmed by experiments.
