The experiment of 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 to determine the degree of degradation and efficiency. The results of photocatalytic experiment showed a good linear relationship between fluorescence quenching degree (F/F₀) and reaction time (t) on fluorescent substance of CdSe/ZnS quantum dot, according to the photocatalytic degradation kinetics equation of CdSe/ZnS quantum dots. The consistency of experimental results was also confirmed with fluorescence spectroscopy and conventional spectrophotometry. Based on this, a new sensitive method was established for efficient determination of photocatalytic degradation fluorescent substance. The present method was helpful to analyze the photocatalytic degradation mechanism of fluorescent substance and provided a theoretical basis and reference to study the photocatalytic degradation on other fluorescent substances.
