Preparation of CeO2/Flake-like CdS Composites as High-Performance Photoanodes for Photoelectrochemical Cathodic Protection

doi:10.15541/jim20190057

Abstract

Abstract:

CeO₂/CdS nanocomposites with the function of storing electrons and physical barrier were fabricated for photocathodic protection through a stepwise synthetic route. The obtained smples were characterized by XRD, TEM, UV-Vis and PL. The photoelectrochemical properties of CeO₂/CdS with different mass ratios were investigated under white light irradiation. The maximum photocurrent density of CeO₂/CdS (mass ratio 0.2 : 1) is 700 μA·cm ^-2 and the potential of the 304 stainless steel coated with CeO₂/CdS (mass ratio 0.2 : 1) shifts to -650 mV (vs. SCE), which is significantly lower than the corrosion potential (-200 mV vs. SCE). The above results indicate that the CeO₂/CdS composites exhibit remarkable photo cathodic properties which are attributed to the heterostructure of CeO₂ nanoparticles and CdS nanosheets, and the structure facilitates the separation of photo-induced electron and hole. Furthermore, the CeO₂/CdS composites can also provide cathodic protection for 12 h in the dark.

Key words: CeO₂/CdS composite, heterostructure, physical barrier, photoelectrochemical cathodic protection
