Design of electrocatalysts and electrodes for CO2 electroreduction to formic acid and formate
Electrochemical carbon dioxide (CO2) reduction reaction (CO2RR) is gaining attraction as it enables the generation of highly valuable chemicals while mitigating greenhouse gas emissions. Numerous efforts have been dedicated to designing efficient catalysts that selectively reduce CO2 into various chemicals such as formic acid/formate, carbon monoxide, methane, ethylene, and ethanol. The efficiency of the CO2RR is evaluated through selectivity to the desired product, overpotential, current density, and stability. This work reviews emerging strategies to improve the CO2RR performance to produce formate/formic acid by tuning catalyst and electrode structures. The catalyst-developing strategies are discussed in terms of engineering electronic and geometric structures, surface oxidation structure, and enlarging surface active area. The design of gas diffusion electrodes and reactor configuration, which are essential in enhancing the efficiency of the electrochemical system, are also mentioned. Finally, insights and perspectives are given on how to overcome the instability of catalysts and limitations of reactor designs.
期刊介绍:
Coordination Chemistry Reviews offers rapid publication of review articles on current and significant topics in coordination chemistry, encompassing organometallic, supramolecular, theoretical, and bioinorganic chemistry. It also covers catalysis, materials chemistry, and metal-organic frameworks from a coordination chemistry perspective. Reviews summarize recent developments or discuss specific techniques, welcoming contributions from both established and emerging researchers.
The journal releases special issues on timely subjects, including those featuring contributions from specific regions or conferences. Occasional full-length book articles are also featured. Additionally, special volumes cover annual reviews of main group chemistry, transition metal group chemistry, and organometallic chemistry. These comprehensive reviews are vital resources for those engaged in coordination chemistry, further establishing Coordination Chemistry Reviews as a hub for insightful surveys in inorganic and physical inorganic chemistry.
