Fe-based air alkaline batteries are promising candidates for large scale energy storage due to their low cost, eco-friendliness and high energy density. In this work, pure iron was studied as negative electrode of Fe-air batteries with and without Na2S added to the KOH alkaline electrolyte in order to bring new insight on the mechanisms of inhibition of the hydrogen evolution reaction (HER) and improvement of the electrochemical performances of the Fe electrode. Electrochemical (CV, galvanostatic discharge), spectroscopic (XPS, ToF-SIMS) and microscopic (SEM) analysis were applied to characterize the effect of the sulfide additive (Na2S) on the electrochemical behavior of Fe electrodes and their chemical and morphological modifications. Surface analysis performed by XPS and ToF-SIMS revealed the formation of a markedly thicker oxide/hydroxide layer. The mechanism of formation of this thick oxide/hydroxide layer is initiated by the adsorption of sulfur (S-ads) at the oxide/metal interface that inhibits the HER during the first stages of electrochemical process and promotes subsequent anodic oxidation. With the Na2S electrolyte additive, Fe(0)/Fe(II) conversion/deconversion is suppressed and charge/discharge proceeds mostly by Fe(II)/Fe(III) conversion/deconversion with improved capacity owing to the porous morphology of the oxide/hydroxide layer.

Insight on passivity of high entropy alloys: Thermal stability and ion transport mechanisms in the passive oxide film on CoCrFeMnNi surfaces

Luntao Wang, Antoine Seyeux, Loic Perriere, Dimitri Mercier, Vincent Maurice, Philippe Marcus

Summary: The ion transport mechanisms in passive films pre-formed on CoCrFeMnNi high entropy alloy surfaces in acid solution were studied in-situ by time-of-flight secondary ion mass spectrometry upon oxidation in 18O2 gas. The bilayer structure of the passive film, with outer Fe, Co-rich and inner Cr, Mn-rich layers, is thermally stable, but with reduction of Fe and Co oxides and formation of Mn oxide in the outer layer above 150 degrees C. At 170 degrees C, the transport mechanism is mainly outward cation diffusion with slower inward oxygen diffusion. The re-oxidation growth rate follows a parabolic law and the value of parabolic constant was determined.

In situ scanning tunneling microscopy study of 2-mercaptobenzimidazole local inhibition effects on copper corrosion at grain boundary surface terminations

Sagar B. Sharma, Vincent Maurice, Lorena H. Klein, Philippe Marcus

Summary: New insight is provided on the local inhibition effects of 2-mercaptobenzimidazole (MBI) on early stage intergranular corrosion of copper in hydrochloric acid solution, showing passivation-like behavior in the Cu(I) oxidation range specific to MBI and the imperfect protection of an anodically formed MBI layer against dissolution. Local accumulation of reaction products in the grain boundary surface regions was found to block preferential dissolution, with different inhibition efficiency observed compared to 2-mercaptobenzothiazole (MBT) effects.

Sagar B. Sharma, Vincent Maurice, Lorena H. Klein, Philippe Marcus

Summary: The study investigated the effects of two organic corrosion inhibitors on grain boundary passivation in copper, revealing that the organic surface layers can block the formation of Cu(I) surface oxide and passivation, but do not entirely suppress residual reactivity.

An XPS and ToF-SIMS study of the passive film formed on a model FeCrNiMo stainless steel surface in aqueous media after thermal pre-oxidation at ultra-low oxygen pressure

Benjamin Lynch, Shova Neupane, Frederic Wiame, Antoine Seyeux, Vincent Maurice, Philippe Marcus

Summary: A combination of X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, and electrochemistry was used to investigate molybdenum and chromium enrichment of a passive film on a model austenitic stainless steel single crystal, as well as the effect of thermal pre-oxidation at 250 degrees C on the film's composition and layering. The study found that pre-oxidation promoted the hydroxylation of chromium and molybdenum, leading to enrichment of these elements in the oxide film, with an increase in both thickness and chromium content of the inner layer under anodic polarization. Additionally, pre-oxidation at 250 degrees C was found to protect against active dissolution during anodic passivation and promote molybdenum enrichment in the outer layer of the passive film.

Summary: This study investigated the effects of water on a 2-mercaptobenzothiazole film pre-formed on copper at low pressure and room temperature using X-ray photoelectron spectroscopy. The results showed that exposure to water vapor led to desorption of 2-MBT molecules not directly bonded to copper, with cleavage of the bond between exocyclic sulphur and copper, while nitrogen remained bonded to copper.

Atomic Scale Insight into Corrosion Inhibition: DFT Study of 2-Mercaptobenzimidazole on Locally De-Passivated Copper Surfaces

Fatah Chiter, Dominique Costa, Vincent Maurice, Philippe Marcus

Summary: The study shows that 2-mercaptobenzimidazole (MBI) can strongly adsorb on different zones of oxide or metal, forming an inhomogeneous organic film to enhance the barrier properties of the passivated surface. This suggests that both species of MBI can heal oxygen and copper low coordinated sites and protect exposed metal surface even when locally defective.

Xiaocui Wu, Frederic Wiame, Vincent Maurice, Philippe Marcus

Summary: The study provides molecular scale insight into the build-up mechanisms of a corrosion inhibiting interface by depositing 2-mercaptobenzimidazole (2-MBI) from the vapor phase onto copper surfaces and characterizing the adsorption mechanisms using X-ray photoelectron spectroscopy. The adsorption of 2-MBI molecules on copper surfaces changes from lying flat to tilting at higher exposure, leading to a densification of the monolayer. The presence of different oxide layers affects the adsorption and bonding behavior of the molecules.
