摘要：
The physicochemical characteristics of nitrogen-modified TiO2/SiO2 and its photocatalytic activity in the oxidation of methyl orange (MO) were studied. Nitrogen-modified TiO2/SiO2 had higher activity than the unmodified samples. The photocatalytic oxidation of MO obeys the Langmuir-Hinshelwood model.
