Photothermal materials are attracting more and more attention. In this research, we synthesized a ferrocene-containing polymer with magnetism and photothermal properties. The resulting polymer was characterized by Fourier-transform infrared (FT-IR), vibrating sample magnetometer (VSM), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Its photo-thermocatalytic activity was investigated by choosing methylene blue (MB) as a model compound. The degradation percent of MB under an irradiated 808 nm laser reaches 99.5% within 15 min, and the degradation rate is 0.5517 min, which is 145 times more than that of room temperature degradation. Under irradiation with simulated sunlight, the degradation rate is 0.0092 min, which is approximately 2.5 times more than that of room temperature degradation. The present study may open up a feasible route to degrade organic pollutants.
光热材料正受到越来越多的关注。在本研究中，我们合成了一种具有磁性和光热性质的含二茂铁聚合物。通过傅里叶变换红外光谱（FT-IR）、振动样品磁强计（VSM）、扫描电子显微镜（SEM）、能量色散X射线光谱（EDS）、X射线光电子能谱（XPS）、X射线衍射（XRD）和热重分析（TGA）对所得聚合物进行了表征。以亚甲基蓝（MB）为模型化合物研究了其光热催化活性。在808nm激光照射下，MB在15分钟内的降解率达到99.5%，降解速率为0.5517min，是室温降解速率的145倍。在模拟太阳光照射下，降解速率为0.0092min，约为室温降解速率的2.5倍。本研究可能为降解有机污染物开辟一条可行的途径。
