We study the role of binders (ionomers) in determining life-span gas diffusion electrodes (GDEs) used for high throughput CO2-to-CO electrolysis. compare two typical ionomer materials (Nafion and Fumion, both are widely preparation Ag nanoparticles-based catalyst inks) to show that when zero-gap membrane/electrode assemblies, Fumion-containing inks superior Nafion-based ones can uphold a very CO-selectivity electrochemical CO2 reduction reaction longer time. This is due ability Fumion containing suppress precipitation inside GDE structure. As Fumion-fixed GDEs significantly less hydrophobic than Nafion-fixed ones, our results contradict accepted opinion it their non-wettability what mostly protects CO2-reducing from flooding. In turn, we argue more important maintain efficient electrolyte drainage pathways structure, explain superiority on this basis.

Abstract Electrochemically reducing CO 2 to more reduced chemical species is a promising way that not only enables the conversion of intermittent energy resources stable fuels, but also helps build closed-loop anthropogenic carbon cycle. Among various electrocatalysts for electrochemical reduction, multifunctional metal–organic frameworks (MOFs) have been employed as highly efficient and selective heterogeneous due their ultrahigh porosity topologically diverse structures. Up now, great progress has achieved in design synthesis active MOF-related catalysts reduction reaction (CO RR), corresponding mechanisms thoroughly studied. In this review, we summarize recent applying MOFs derivatives RR, with focus on strategies electrolyzers. We first discussed different RR products introduced commonly applied electrolyzer configurations current system. Then, an overview several categories (CO, HCOOH, CH 4 , 3 OH, multi-carbon chemicals) generated from or via was discussed. Finally, offer some insights perspectives future development reduction. aim provide new into field further guide research large-scale applications.

The electrocatalytic reduction of carbon dioxide (CO2RR) is a crucial technology to develop the decarbonisation strategy for circularity and producing solar fuels substituting fossil fuels. This viewpoint discusses role electrode reactor design as main factor in determining performance CO2RR, at least under reaction conditions relevant industrial scalability, evidencing need overturn current strategic vision focused more on improving characteristics materials. Many parameters characterising performances (such Faradaic efficiency, selectivity potential onset, besides density) are strongly influenced typically dominated (under conditions) by effective population adspecies surface, which is, turn, related mass control transport resistances, local pH changes, multiphase boundaries, wettability other aspects. Even preliminary screening catalysts could be incorrect, not operating representative conditions, thus without properly choosing reactor. Advanced electrode/reactor designs, e.g., based gas-diffusion electrodes (GDEs) that avoid having liquid electrolyte (zero-gap design), necessary improve CO2RR scalability applications. situ catalyst nanoparticle reconstruction may depend these Electrochemical characterization methods like electrochemical impedance spectroscopy (EIS) right approach study reactions, providing indications controlling elements determine electrocatalyst/electrode performances.

Climate change, caused by greenhouse gas emissions, is one of the biggest threats to world. As per IEA report 2021, global CO2 emissions amounted around 31.5 Gt, which increased atmospheric concentration up 412.5 ppm. Thus, there an imperative demand for development new technologies convert into value-added feedstock products such as alcohols, hydrocarbons, carbon monoxide, chemicals, and clean fuels. The intrinsic properties catalytic materials are main factors influencing efficiency electrochemical reduction (CO2-RR) reactions. Additionally, electroreduction mainly affected poor selectivity large overpotential requirements. However, these issues can be overcome modifying heterogeneous electrocatalysts control their morphology, size, crystal facets, grain boundaries, surface defects/vacancies. This article reviews recent progress in reactions accomplished surface-defective identifies significant research gaps designing highly efficient electrocatalytic materials.
