Summary: Electrochemical CO2 reduction reaction (CO2RR) is a promising technology for clean energy economy. This study investigates the mechanism of CO2RR using ab initio molecular dynamics simulations. The results show that the presence of K cations promotes CO2 activation and inhibits the competitive hydrogen evolution reaction (HER) at the inner-sphere interface. A comprehensive free energy diagram of CO2RR and HER is derived, demonstrating the critical role of cations in facilitating CO2 adsorption while suppressing hydrogen evolution.

Summary: Carbon dioxide/monoxide (CO2/CO) electrolysis has the potential to convert emissions into multicarbon products, but current systems suffer from low energy and carbon efficiencies. In this study, the researchers identified uncontrolled gas/ion distributions as the source of these inefficiencies and developed a strategy to block cation migration to the catalyst surface using a covalent organic framework (COF). The COF-mediated catalyst achieved a single-pass carbon efficiency of 95%, an energy efficiency of 40%, and a current density of 240 mA cm(-2) during 200 hours of electrosynthesis of multicarbon products from CO.

Summary: In this study, the influence of solvent molecules on CO2 reduction reaction (CO2RR) over single metal atom catalysts was systematically investigated. It was found that water molecules not only affect the electronic state of the metal atom, but also the energy and conformation of CO2RR intermediates, providing useful insights for the design of efficient CO2RR single atom catalysts.

Summary: The hydrodynamics of electrochemical CO2 reduction (CO2R) systems have a significant impact on catalyst activity and selectivity. Previous studies have mainly focused on laminar and CO2-sparged systems, while this study investigates a wide range of hydrodynamics using electrolyte recirculation systems. It is found that increased hydrodynamics at the electrode surface affect the Tafel slopes of ethylene and methane, indicating that mass transport plays a crucial role in determining reaction mechanisms and product distribution. The study highlights the importance of considering mass transport conditions in CO2R mechanistic research. Additionally, the analysis shows that organic coatings can protect active sites from hydrodynamic effects and enhance the reduction of CO to desired products.

Summary: This paper systematically discusses the effects of surface and interface structures in Cu-based catalysts for the electrochemical CO2 reduction to valuable ethylene and ethanol. The key steps for ethylene production are C-C coupling, which can be enhanced by tuning the surface structures of the catalyst, and for ethanol production, it is the controllable hydrodeoxygenation of C-2 intermediates, which can be achieved by tuning the stability of oxygenate intermediates through the metallic cluster induced special atomic configuration and bimetallic synergy induced the double active sites on the catalyst surface. The structure-performance relationships provide guidance for the design of Cu-based catalysts for highly efficient reduction of CO2.

Summary: The study utilized an anti-swelling anion exchange ionomer (AEI) to optimize the local environment for CO2 electroreduction to C2+ products, achieving higher C2+ selectivity. In situ measurements showed that the anti-swelling backbone and N(CH3)(3)(+) groups synergistically regulated the local pH level and water content, leading to enhanced C2+ production. The anti-swelling AEI-modified catalyst demonstrated improved Faradaic efficiency and power conversion efficiency compared to most reported powder catalysts.

Summary: The electrical double layer at the electrode-electrolyte interface plays a significant role in electrochemical reactions, especially for the electrochemical CO2 reduction reaction. Larger alkali cations are usually found to enhance the activities of catalysts. However, the underlying mechanism of this cation effect is still not clear. This perspective provides an overview of the current understanding, based on latest experimental and computational findings, of the complex nature of the cation effect and discusses how it can be leveraged, along with other optimization conditions, to enable highly efficient CO2 reduction.

Summary: The study focuses on the electrochemical reduction of CO2 at gold electrodes under mildly acidic conditions. Increasing the CO2 partial pressure enhances the rate of CO2 reduction and suppresses hydrogen evolution, leading to high Faradaic efficiencies close to 100%. By suppressing hydrogen evolution and using protons for water formation, the study derived a general design principle for acid CO2 electrolyzers to match the mass transfer of protons to the electrode surface.
