制备了铂修饰氧化铟纳米棒(Pt/IONR),并将其用于光催化降解全氟辛酸(PFOA)。在700 °C下合成的具有3wt% Pt的IONR在PFOA的降解中表现出最佳活性。光催化效率的提高主要来自于两个方面:Pt的负载和棒状结构,它可以促进光的捕获和提高载流子的分离速率。此外,光催化剂表面的氧空位也可能加速PFOA的降解。这些结果表明,Pt/IONR是一种很有前途的光催化剂,可用于PFOA的降解。
Platinum modified indium oxide nanorods (Pt/IONRs) were synthesized and applied for photocatalytic degradation of perfluorooctanoic acid (PFOA). IONRs synthesized at 700 °C with 3 wt% Pt exhibited optimal activity in the degradation of PFOA. The improvement of photocatalytic efficiency is mainly ascribed to two aspects: the load of Pt and the rod-like structure, which could promote light harvesting and enhance the separation rate of charge carriers. Besides, the oxygen vacancies on the surface of photocatalyst may accelerate the degradation of PFOA as well. These results suggested that Pt/IONRs could be a promising photocatalyst for PFOA degradation.
