制备了半导体纳米材料，并研究了其对玉米赤霉烯酮(Zen)的降解效率。采用传统的热裂解方法合成了光催化材料g-C3N4。用X射线衍射仪、傅里叶变换红外光谱、X射线光电子能谱、扫描电子显微镜和透射电子显微镜对其结构进行了表征。光催化降解实验表明，在紫外灯(254 nm，185 nm)照射下，g-C3N4具有光催化作用，为实际粉末样品中Zen的降解提供了一种新的方法。探索了在实际粉末样品中光催化降解主要标准物质ZEN和ZEN的实验条件。用高效液相色谱-质谱法分析了Zen的降解产物。在各最佳实验条件下，对实际粉末样品中的主要标准物质ZEN和ZEN的降解率分别为96.0%和50.0%。研究结果为g-C3N4光催化降解实际粉状样品中的霉菌毒素提供了理论参考和实践依据。
A semiconductor nano-material was prepared, and its degradation efficiency of zearalenone (ZEN) was studied. The photocatalytic material g-C3N4 was synthesized by the traditional method of hot cracking. Its structure was characterized by XRD, FTIR, XPS, SEM and TEM. The photocatalytic degradation experiment showed that under the irradiation of UV lamp (254 nm, including 185 nm), g-C3N4 could induce photocatalytic effect, which provided a new method for the degradation of ZEN in real powder samples. The experimental conditions of photocatalytic degradation of the primary reference material of ZEN and ZEN in real powder samples were explored. And the degradation products of ZEN were analyzed after HPLC-MS. Under each optimal experimental conditions, the degradation rate on primary reference material of ZEN and ZEN in real powder samples was 96.0% and 50.0%, respectively. The results in this work provide a theoretical reference and practical basis for the photocatalytic degradation of mycotoxin in real powder samples by g-C3N4.
