Cerium oxide materials exhibit remarkable properties, positioning them as highly effective, environmentally friendly solutions across diverse applications. This chapter provides a comprehensive overview of fundamental concepts and technological methodologies related to cerium oxide (CeO2) and doped ceria-based materials. Emphasis is placed on electrochemical deposition, spray pyrolysis, and the sol-gel approach for synthesizing thin and thick layers of ceria. The versatility of these materials is explored, spanning from corrosion protection layers and specialized ceramic elements for sensor applications to components for solid oxide fuel cells (SOFCs) and electrodes for water-splitting cells. Additionally, the chapter delves into the promising applications of recently developed ceria-based nanomaterials in various fields, marking some advanced methods for CeO2-based materials synthesis. The key findings are succinctly summarized in the concluding section.

“…Therefore, new environmentally friendly alternatives have sparked a great deal of research interest in recent years. Various studies have then followed up, developing formulations based on rare earth salts or compounds containing molybdenum [7–9], zirconium [10,11] and titanium [12,13]. Among the low environmental impact compounds, vanadium has drawn attention, as a pre-treatment, for its peculiar self-healing properties and corrosion protection ability, proving to be a good candidate to replace traditional processes such as zinc phosphating.…”

The electroless deposition of a novel vanadium-based conversion coating (VCC) on carbon steel was investigated varying parameters as vanadium salt concentration, immersion time, bath pH and temperature. The novelty resides on the deposition of a protective layer from a V 4+ solution comprising green reducing agents like ascorbic and citric acids. The VCC was found to be amorphous, composed by closely packed particles rich in vanadium oxides/ hydroxides. Corrosion resistance was evaluated by linear polarization resistance, Tafel extrapolation and electrochemical impedance spectroscopy. Such conversion coating provided an optimum corrosion performance for steel substrates immersed in sulphates and chlorides rich solutions. An optimum was achieved with a 0.1 M KVO 3 solution held at 45°C, at pH = 3 and a deposition time of 10 min. Higher values of the latter parameters did not provide any further improvements: the formation of cracks during the dehydration process compromised the coating integrity.

Purpose The purpose of this paper is to confirm the importance of using metal–organic frameworks (MOFs) in the field of corrosion control due to their potential use as corrosion inhibitors. Design/methodology/approach NH2–MIL–101(Cr), an amine-functionalized chromium-based MOF [Cr(III)-MOF], was prepared by solvothermal technique. Thereafter, Cr-MOF was used as an anticorrosion additive for mild steel (MS) in 1 m HCl solution. This inhibition behavior was tested by electrochemical tests including electrochemical impedance spectroscopy and potentiodynamic polarization (PDP). Findings Increasing the added amount of Cr-MOF enhances its inhibition performance, which attained 96.40% at 30 ppm. The obtained data from PDP measurements describe Cr-MOF as a mixed-type inhibitor. Based on SEM/EDS and FTIR analysis, the adsorption of Cr-MOF on the surface of MS that prevents MS corrosion has been demonstrated. Furthermore, Langmuir model is the most adequate adsorption isotherm for the obtained experimental data. Originality/value This study revealed that NH2–MIL–101(Cr), an amine-functionalized chromium-based MOF (Cr(III)-MOF), is a potential corrosion inhibitor for MS in 1 m HCl solution.
