摘要

纯锌涂层在可见光下没有抗菌作用,在生物污垢后很容易失去保护性能。在本研究中,我们使用电沉积方法将Fe3+掺杂的碱化g-C3N4(AKCN-Fe)偶联到现有的锌涂层中,制备了一种新的抗菌锌复合涂层,并表明AKCN-Fi增强了锌涂层在可见光下的抗菌性能。我们将这种增强归因于AKCN-Fe的高光催化性能、高负载量和良好的分散性。此外,清除剂实验和电子顺磁共振(EPR)测量支持了复合涂层的光催化抗菌机制,表明超氧化物(·O2−)和羟基自由基(·OH)分别起主要和次要作用。

Developing high photocatalytic antibacterial Zn electrodeposited coatings through Schottky junction with Fe3+-doped alkalized g-C3N4 photocatalysts

Pure Zn coatings easily lose their protective performance after biofouling because they have no antibacterial effect under visible light. In this study, we fabricate a new antibacterial Zn composite coating using electrodeposition to couple Fe3+-doped alkalized g-C3N4 (AKCN-Fe) into an existing Zn coating and show that the AKCN-Fe enhances antibacterial property of the Zn coating under visible light. We attribute this enhancement to the high photocatalytic performance, high loading content, and good dispersion of AKCN-Fe. In addition, the photocatalytic antibacterial mechanism of the composite coating is supported by scavenger experiments and electron paramagnetic resonance (EPR) measurements, suggesting that superoxide (·O2) and hydroxyl radical (·OH) play main and secondary roles, respectively.
