Overview of the impact of nickel-based catalyst on corrosion mechanism for steel

With the rapid development of world industry, the adverse impact of steel corrosion on environmental resources and economic development cannot be underestimated. Oxygen corrosion and hydrogen evolution corrosion are two important reactions in steel. To effectively prevent corrosion of steel, many catalytic materials have been developed. In particular, some nickel-based materials, because of their controllable structure, excellent performance, low carbon environmental protection and other advantages, can well enhance the corrosion resistance of steel. This paper first summarizes the concept, basic reaction mechanisms, and influencing factors of steel corrosion. Then, this paper mainly reviews the latest progress in the research of various nickel-based catalysts. Particular attention is paid to the preparation strategies, catalytic properties and deactivation mechanisms of these catalysts, as well as the methods used to improve performance. Finally, the current challenges and future development directions of high activity and durability electrocatalysts are presented.
