查询词典 irradiation

The photocatalytic degradation property of ZnM2O4 (M=Cr, Mn, Fe) nanoparticles was investigated by using methyl orange, acid red B and reactive red K-2G as model pollutants under the irradiation of a mercury-vapor lamp (λ＞400 nm) or sunlight.

The TiO2 synthesized by normal and reverse micelles as templated were applied for phot ocatalytic of Rhodamine B and organic toxic small molecule 2.4-dichlorophenol under ultraviolet irradiation. Oxidation species and photodegradation products in the photoreaction process were detected for studying their photocatalyst properties. The results showed that: the R-TiO2 had a better photocatalysis property under UV irradiation when photodegradation of RhB and DCP compared to the N-TiO2. After 160min, the mineralized rate of RhB can be 95%. And the oxidative species was mainly referred to OH radical.
