The NaYF₄:Yb, Tm nanoparticles coated with anatase TiO 2 (NaYF₄:Yb,Tm@TiO₂) are synthesized by hydrolysis of the titanium precursor to form a core-shell composite. The synthesized composite are characterized by TEM, XRD, UV-Vis DRS and FL. Under UV-Vis-NIR (200~2500 nm) irradiation, NaYF 4:Yb,Tm@TiO₂ have a photocatalytic degradation effect and result in production of strong oxidizing free radicals, which can effectively degrade the OTA. After further optimization, the optimum loading of catalyst is found to be 10 mg/mL. Under pH of 6.2 and 500 W xenon lamp (light source), the photocatalytic degradation efficiency of 5 μg/mL OTA can reach up to 98.7% after 30 min. This photocatalytic reaction follows the first-order kinetics. Two products C₁₁H₉O₅Cl and C₁₉H₁₇ClNO₄ are formed during the OTA degradation, which have been assessed by ultraperformance liquid chromatography/quadrupole time-of-flight mass spectrometry, the mass-to-charge ratios (m/z) are 256.015 and 360.061, respectively. The present study may open a new avenue to degrade other toxin., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null,

A，OTA）的降解效率，分析了OTA在光催化降解过程中的产物，为霉菌毒素的脱除提供了新方法。采用钛酸酯水解法，在上转换材料NaYF₄：Yb，Tm表面包覆锐钛矿TiO₂纳米层形成核壳结构光催化材料NaYF₄：Yb，Tm@TiO₂，借助TEM、XRD、UV-Vis DRS和FL对其进行了结构表征。光催化降解实验表明，在紫外—可见—近红外光（200~2500 nm）辐照下，NaYF₄：Yb，Tm@TiO₂可以产生光催化效应，释放活性氧自由基，实现对OTA的降解。进一步优化光催化降解实验条件，结果表明，当光催化材料用量为10 mg/ml、溶液pH为6.2时，初始浓度为5 μg/mL的OTA在500 W氙灯光照30 min后降解率达98.7%，反应符合一级动力学方程。利用超高效液相色谱-四级杆飞行时间质谱技术研究了OTA的降解产物。分析鉴定了2种产物，质荷比（m/z）为256.015和360.061，推测其分子式分别为C₁₁H₉O₅Cl和C₁₉H₁₇ClNO₄。研究结果为NaYF₄：Yb，Tm@TiO₂光催化降解霉菌毒素提供了理论参考和实践依据。, correspAuthors=null,
