Tuning Reconstruction Level of Precatalysts to Design Advanced Oxygen Evolution Electrocatalysts

Abstract

Surface reconstruction engineering is an effective strategy to promote the catalytic activities of electrocatalysts, especially for water oxidation. Taking advantage of the physicochemical properties of precatalysts by manipulating their structural self-reconstruction levels provide a promising methodology for achieving suitable catalysts. In this review, we focus on recent advances in research related to the rational control of the process and level of surface transformation ultimately to design advanced oxygen evolution electrocatalysts. We start by discussing the original contributions to surface changes during electrochemical reactions and related factors that can influence the electrocatalytic properties of materials. We then present an overview of current developments and a summary of recently proposed strategies to boost electrochemical performance outcomes by the controlling structural self-reconstruction process. By conveying these insights, processes, general trends, and challenges, this review will further our understanding of surface reconstruction processes and facilitate the development of high-performance electrocatalysts beyond water oxidation.

Double Perovskite Oxides Bringing a Revelation in Oxygen Evolution Reaction Electrocatalyst Design

“…show that the reconstruction mechanism depends upon the potential applied and the reaction time for the Co‐based catalyst [107] . Therefore, the reconstruction of the surface varies along with the materials used, applied voltage and as well as on reaction conditions [19] …”

“…Following this new idea, an array of novel perovskites were generated with rational surface reconstruction with promising OER activity. [17][18][19][20][21][22] To date, the majority of the efforts for generating OERactive perovskites have been comprised of refining surface area (SA) and improving the overall intrinsic activity. These studies indicated that the perovskite-driven OER activity maximizes when the B-site e g electron-filling state is optimized.…”

Dynamic Surface Evolution of Metal Oxides for Autonomous Adaptation to Catalytic Reaction Environments

“…[57] Taking all the above into account, in this section, we introduce previously reported studies in which surface reconstruction occurs with the leaching of metal ions (i.e., in-and-out-type ion movement) and its electronic structural effects during catalytic tests. Although several recent reviews have well addressed diverse examples of phase evolution during electrocatalysis, [58] our review is providing well-organized design guidelines by distinguishing the type of metal oxide (e.g., TM and precious metal), electrolyte conditions (e.g., alkaline and acidic electrolytes), and strategies (e.g., facilitation and protection). [59] Before looking at experimental examples, theoretical predictions of the leaching and surface reconstruction processes can be of great help during the material design stage.…”

Enhanced Electrochemical Water Oxidation Activity by Structural Engineered Prussian Blue Analogue/rGO Heterostructure

“…The Fe-based transition-metal catalysts present low-cost relative to current commercial noble metal catalysts and have high catalytic activity and stability under alkaline conditions [ 11 , 12 ]. It is worth noting that Prussian blue-like material is a typical metal-organic framework structure material with an open skeleton, adjustable components, and a large number of unsaturated coordination atoms [ 13 , 14 ].…”
