The Application of Modified Nanometer Titanium Dioxide in Degradation of Methyl Orange Solution

Abstract:

The nanometer TiO₂ thin membrane on different substrates doped with La³⁺ was prepared from Ti (OC₄H₉)₄ and La (NO₃)₃ by Sol-Gel processing using dipping technique. The photocatalytic activity of membrane at different doping concentration in photocatalytic methyl orange was studied. The result showed that both the degraded rate and the optimum concentration depended on the change of doping concentration and substrates. When TiO₂ thin membrane was doped with 0.5 La³⁺ on the substrates of glazed ceramic, aluminum and stainless steel, TiO₂ membrane has the maximum degradation rate.
