CO₂ Reduction: Highly Efficient Electrochemical CO₂ Reduction Reaction to CO with One‐Pot Synthesized Co‐Pyridine‐Derived Catalyst Incorporated in a Nafion‐Based Membrane Electrode Assembly (Adv. Energy Mater. 39/2020)

Abstract

In article number 2001645, Naohiro Fujinuma, Samuel E. Lofland and co‐worker reduce carbon dioxide from exhaust sites to carbon monoxide using a cobalt‐pyridine catalyst in an electrochemi cal process with the high energy efficiency needed for large‐scale commercialization. When the electricity for this reaction is supplied by renewable resources, this carbon cycle decreases greenhouse gases while the end product serves as feedstock for plastics, further reducing reliance on fossil fuels.

Polymer Electrolytes with High Ionic Concentration for Fuel Cells and Electrolyzers

“…A much improved acid retention can be obtained by introducing more strong ionic pair interactions vs traditional acid–base interactions. For example, recent papers demonstrated a high-performance intermediate-temperature fuel cell using an ion-pair-coordinated ionomeric binder at 200–220 °C. , Other systems such as direct ammonia fuel cells, CO 2 electrolyzers, reformed methanol fuel cells, and steam electrolyzers that work at 100–300 °C are possible with advanced high-IEC polymer electrolytes.…”

Structural Optimization of Reactor for the Enhancement of CO2 Electrochemical Reduction Based on Gas–Liquid Mixing Flow Model

“…[37][38][39] To overcome these challenges, researchers are actively exploring new reaction designs and improving electrochemical reduction systems from the perspective of interdisciplinary integration. For example, microchannel design technology, [40][41][42] microreactor technology, [40][41][42] ceramic electrode technology, [43] membrane reaction technology, [23,44,45] and multiphase catalytic system research. [46] Gas diffusion electrodes are also used to achieve industrial-scale current densities.…”

“…[14][15][16][17][18][19] Some researchers have improved the reaction efficiency by adjusting the catalyst's structure, such as altering the catalyst's elemental composition [20][21][22] and controlling the catalyst's lattice structure. [23][24][25] Conversely, some have studied the catalytic system from the perspective of the carrier fluid, by adjusting the solute composition of the aqueous electrolyte or selecting organic electrolytes. [14,17,26] However, research in this domain faces three salient challenges.…”
