Understanding the metal ion-ligand responsible in the plasma-assisted electrochemical reactions for optimizing chemical stability

Abstract

In this work, magnesium-based inorganic layer was prepared via low temperature-interfacial plasma electrolysis (LT-PE) at different ratios of metal ions/organic ligands in order to optimize the chemical stability and understand the role of coordination complexes in plasma-assisted electrochemical reactions (PAE). Optimal complexes having a metal-capped core formed by melamine (MEL) terminated with amino groups have less porous surface compared to that of simple structures. This is due to the incorporation of different particles into the resulting coating. Accordingly, such an inorganic layer contains metal oxide nanoparticles and stable magnesium-aluminate since chemical transformations of complexes are remediated to a greater extent via interfacial plasma electrolysis. The conformal inorganic layer prevents corrosion by a synergy formed between the porous microstructure and metal oxides nanoparticles resulting from thermal analysis of the unstable Ni-MEL and Pb-MEL complexes. The role of coordination complexes after disruptive events, which confirms the formation of sealing inorganic layer with increased concentrations of MEL (Ni2+ and Pb2+) is deliberated using the density functional theory (DFT).
