Atomic-level engineering Fe₁N₂O₂ interfacial structure derived from oxygen-abundant metal–organic frameworks to promote electrochemical CO₂ reduction

Abstract

Atomically-precise preparation and atomic-level understanding on the single-atomic active sites with unique coordination structures in electrocatalysts for CO2 reduction reaction (CO2RR) remain a challenge. Here, we report a strategy of...

Nature‐Inspired Design of Molybdenum–Selenium Dual‐Single‐Atom Electrocatalysts for CO2 Reduction

“…[ 3 ] Nevertheless, the current research efforts on nitrogen‐doped carbon‐based SAs for ECR are focused mainly on Fe, Co, and Ni SAs. [ 4 ] Exploring new catalytic sites at the atomic scale may be an effective way to reveal the structure–performance relationship for providing new perspectives in the rational design of ECR electrocatalysts.…”

Rational design of atomic site catalysts for electrochemical CO2reduction

“…81 In addition, some carboxyl-coordinated MOFs (such as Zn-MOF-74) can further enrich the coordination environment of ASCs by introducing O atoms, thereby optimizing the electronic structure and ECR performance. 82 Besides the MOF confinement strategy, some other porous materials (such as covalent-organic frameworks (COFs) and zeolites) have also been used to fabricate ASCs through spatial confinement. 83,84 It should be noted that supports or their derivatives are required to have a certain conductivity for the ECR reaction.…”

Transformation mechanism of high-valence metal sites for the optimization of Co- and Ni-based OER catalysts in an alkaline environment: recent progress and perspectives

“…In fact, OERs provided protons and electrons in the overall catalytic system, which was related to the overall efficiency of the electrochemical reaction. [25][26][27][28][29][30][31] The OER involved a fourelectron transfer process leading to its kinetic depression. This might lower the efficiency of the overall reaction, but OER catalyst optimization for the overall reaction has a huge room for improvement.…”
