Photocatalytic degradation on fluorescent substance core/shell CdSe/ZnS quantum dots by Nano-TiO2 (P25) under visible light-induced was investigated. The degradation rate was analyzed and evaluated by determining the absorbance of degradation substance, so as to determine the degree and efficiency of degradation. The photocatalytic experiment results showed that the fluorescence quenching degree (F/F0) of CdSe/ZnS quantum dots was linear with the reaction time (t), which was consistent with the photocatalytic degradation kinetics equation of CdSe/ZnS quantum dots. The consistency of experimental results was also confirmed with fluorescence spectroscopy and conventional spectrophotometry. In the experiment, an efficient and sensitive method was established for the detection of light catalytic degradation of fluorescent substances. The presented method was helpful to analyze the photocatalytic degradation mechanism of fluorescent substance and provided a theoretical basis and reference for the investigation of photocatalytic degradation on other fluorescent substances.
