Abstract:Titanium dioxide nanoparticles were prepared from the cheap inorganic salt by the sol-gel method and used in the photocatalytic degradation of acetic acid in the aqueous solution. The experiment results show that the amount and heat-treated temperature of TiO_2, the pH value and concentration of solution considerably affect the process of the degradation. The influence of the coexistent inorganic ions on the photodegration of acetic acid was investigated.
Keywords:titanium dioxide nanoparticle  acetic acid  photocatalytic degradation
