Here with, a porphyrin-squaraine-based panchromatic sensitizer was designed, synthesized perfectly and confirmed by its spectral analysis. SP-TBU showed a wide energy absorption in the visible and NIR region, which is very important criteria for photocatalytic activity studies. With this dye, a new TiO2-porphyrin catalyst was prepared and studied using SEM, TEM, UV–vis diffused reflectance spectra
在此基础上,设计了卟啉-方酸类全色敏化剂,对其进行了完美合成并通过其光谱分析得到了证实。SP-TBU在可见光和近红外区域显示出广泛的能量吸收,这对于光催化活性研究是非常重要的标准。使用这种染料,可以制备新的TiO 2-卟啉催化剂,并使用SEM,TEM,UV-vis漫反射光谱,FT-IR光谱,XPS和EDS分析进行研究。研究了可见光下亚甲基蓝降解的光催化活性,并与裸露的TiO 2和(4,4',4'',4‴-(卟啉-5,10,15,20-四基)四(苯甲酸)进行了比较。含和不含H 2 O 2的TiO 2(TCPP-TiO 2)。光催化活性性能的顺序为TiO 2
