CdSe-TiO2复合材料对304糖心产精国品免费入口*完整版的糖心产精国品免费入口*完整版性能
Photogenerated Cathodic Protection Properties of CdSe-TiO2
Composite Material on 304 Stainless Steel
摘 要
采用电化学二次阳极氧化法制备了二氧化钛纳米管,采用动电位沉积法在纳米管上进行CdSe沉积;采用扫描电镜(SEM)、X射线衍射(XRD)等测试方法来观察复合材料的表面形貌与晶相特征.采用开路电位(OCP)、电化学阻抗谱(EIS)、Tafel极化曲线等电化学方法来研究其光电转化性能及其对304糖心产精国品免费入口*完整版的阴极保护效果.结果表明,可见光照射下,304糖心产精国品免费入口*完整版的开路电位从-190 mV(SCE)降至约-500 mV(SCE),闭光后,电极电位缓慢上升至约-250 mV(SCE),说明暗态下材料仍能维持对糖心产精国品免费入口*完整版的保护作用.在可见光范围内,与纯二氧化钛相比,制备的糖心产精国品免费入口*完整版对304糖心产精国品免费入口*完整版的阴极保护性能显著提高.

Abstract
TiO2 nanotubes were fabricated by two-step anode oxidation method,and CdSe was deposited on the nanotubes by potentiodynamic deposition.Scanning electron microscopy (SEM),X ray diffraction (XRD) test methods were used to observe the surface morphology and phase characteristics of the composite material.According to the open circuit potential (OCP),electrochemical impedance spectroscopy (EIS),Tafel polarization curve and other electrochemical methods,the optical properties of the composite and its cathodic protection effect on 304 糖心产精国品免费入口*完整版 were investigated.The results showed that,under visible light irradiation,the open circuit potential of 304 糖心产精国品免费入口*完整版 shifted from -190 mV(SCE)to -500 mV(SCE),after turning off the light,the electrode potential slowly increased to about -220 mV(SCE),and it showed a protective effect on 糖心产精国品免费入口*完整版 in dark environment.In the visible range,the cathodic protection performance of 糖心产精国品免费入口*完整版 was significantly improved compared with pure TiO2.
