采用静电纺丝技术研究了含TiO2纳米粒子的丝素（SF）的光催化性能。成功制备了静电纺SF/TiO2席子，并采用XRD、FE-SEM、XPS、XDS、FTIR和BET等技术对其进行了表征。通过对太阳光照射下水中四种农药（boscalid、hexythiazox、pyraclostrobin和trifloxystrobin）的降解能力来评价这些材料的光催化效率。为了确定催化剂的最大降解效率，研究了催化剂负载对不同农药消失动力学的影响。添加TiO2后，降解率显著提高。然而，当TiO2负载从25 mg增加到50 mg时，大多数化合物的TiO2负载没有显著差异（p < 0.05）。因此，我们选择了含有25 mg TiO2的SF垫。因此，开发了一种新的、简单的方法来制备具有光催化活性、安全性和潜在应用于农药污染水净化的材料。采用静电纺丝技术研究了含TiO2纳米粒子的丝素（SF）的光催化性能。
The photocatalytic properties of silk fibroin (SF) incorporating TiO2 nanoparticles using an electrospinning technique were examined. Electrospun SF/TiO2 mats were successfully prepared and characterized by different techniques (XRD, FE-SEM, XPS, XDS, FTIR and BET). The photocatalytic efficiency of these materials were assessed by their ability to degrade four pesticides (boscalid, hexythiazox, pyraclostrobin and trifloxystrobin) in water exposed to solar irradiation. The effect of catalyst loading on the disappearance kinetics of the different pesticides was studied in order to determine the maximum degradation efficiency. The degradation rate significantly increases upon adding the TiO2. However, no significant differences (p < 0.05) were observed when the TiO2 loading was increased from 25 to 50 mg for most compounds. Thus, SF mats with 25 mg of TiO2 were selected. Therefore, a new and simple approach to produce materials with photocatalytic activity, safety and potential application in the purification of water contaminated by pesticides has been developed. The photocatalytic properties of silk fibroin (SF) incorporating TiO2 nanoparticles using an electrospinning technique were examined.
