The UIO-66/Bi2S3 photoanode prepared through solvothermal method demonstrates enhanced redox reaction activity and charge carrier migration capability, providing effective protection for stainless steel cathodic protection.
UIO-66/Bi2S3 photoanode was prepared by a simple solvothermal method. The use of UIO-66 nanocrys-talline endows the photoanode with more active sites for redox reaction and good charge carrier migration capability, while Bi2S3 nanorods were used as sensitizer and deposited on the surfaces of UIO-66 using a hydrothermal method. The results showed that UIO-66 can provide protection for 304 stainless steel (SS), and UIO-66/Bi2S3 photoanode can negatively shift the potential of 304 SS to - 0.85 V, which can meet the requirements of industrial potential for steel cathodic protection.
