When used in an environment where oceans and magnetic fields interact, the corrosion behavior of this alloy is currently not well understood. In this study, immersion experiments and electrochemical tests have been used to explore its corrosion behavior under conditions of no magnetic field, a uniform parallel magnetic field, and a vertical magnetic field with a magnetic field. The results indicate that the presence of a magnetic field accelerates corrosion while suppressing pitting and intergranular corrosion of the alloy. Moreover, compared to the perpendicular magnetic field, the impact is more pronounced when applying a parallel magnetic field due to the synergistic effect of Lorentz force and magnetic field gradient force. Additionally, the presence of Si elements affects the formation of Co oxide passivation film, which reduced the corrosion resistance of the alloy under both magnetic and non-magnetic field conditions.

The enhanced performance of MOF-modified electrodes is primarily attributed to the inherent properties of MOFs, such as substantial surface area, pore size, analyte adsorption capacity, and their role in stabilizing electrocatalytic centers. The chemical and thermal stability of MOFs during electrode production and application significantly contributes to the improvement of their performance. To realize optimal performance, future investigations are crucial, emphasizing MOFs with proven chemical and thermal stability under analysis conditions, coupled with efficient adsorption capacities for diverse analytes. The synthesis of novel MOFs using functionalized polytopic organic ligands with a superior affinity for specific analytes is also recommended. Anticipating rapid evolution in research on MOF-modified electrodes, interdisciplinary collaboration is essential. Researchers from diverse scientific areas are expected to recognize the attractiveness of this research field for developing new tools for trace analyses, biological molecules, and pesticides. The collaborative development of MOF-modified electrodes necessitates cooperation between inorganic chemists and analytical chemists experienced in electroanalysis, as the optimization process demands a combination of synthesis and analytical expertise.
