Surface dynamic reconstruction of Ni-based catalysts for electrooxidation reaction

Ni-based materials, widely recognized for their exceptional catalytic properties, experience structural transformations that profoundly influence their performance characteristics and operational stability. To deeply understand the reconstruction mechanism of Ni-based catalysts, this review systematically summarizes the advanced strategies tailoring the dynamic reconstruction process, including electrochemical activation, defect engineering, partial etching, ionic doping, and heterostructure construction. Furthermore, we discuss the implications of these surface transformations on catalytic activity, highlighting their role in optimizing reaction pathways and enhancing overall efficiency in various electrooxidation reactions, such as oxygen evolution reaction (OER), urea oxidation reaction (UOR), glycerol oxidation reaction (GOR), hydroxymethylfurfural oxidation reaction (HMFOR), and ammonia oxidation reaction (AOR). By summarizing recent research findings, this review aims to provide a systematical summary of how surface dynamics can be harnessed to improve the design of Ni-based catalysts for a variety of electrooxidation applications, paving the way for advancements in energy conversion and storage technologies.
