Corrosion protection of large-scale 304 stainless steel via Co-MOF coated the spaced TiO2 nanotube array photoanodes
In this paper, TiO2 nanotube arrays with gap characteristics were designed and fabricated. Moreover, by adjusting the ratio of metal ions to ligands (1:20), a fully coated Co-MOF/TiO2 composite photoanode was obtained; Secondly, tests such as XPS and EPR were adopted and combined with theoretical calculations to verify the construction of Type II heterojunctions, which promoted the separation of photogenerated electron-hole pairs and thereby enhanced the cathodic protection effect of the composite photoanode. Finally, to promote green and environmentally friendly anti-corrosion materials, an in-depth study was conducted on the anti-corrosion and anti-pitting effects of composite photoanodes on 304SS with different application areas (1cm2,25cm2,100cm2).
期刊介绍:
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
