High carbon utilization in CO2 reduction to multi-carbon products in acidic media

Yi Xie et al.

Summary: Renewable electricity-powered CO2 reduction to multi-carbon (C2+) products is a promising route for low-carbon-footprint fuels and chemicals. Acidic conditions offer a solution to the consumption of input CO2 by the electrolyte, but also promote the hydrogen evolution reaction. This study presents a design strategy that suppresses the activity of hydrogen evolution reaction by maximizing the co-adsorption of CO and CO2 on Cu-based catalysts.

Structure of the (Bi)carbonate Adlayer on Cu(100) Electrodes

Reihaneh Amirbeigiarab et al.

Summary: In situ scanning tunneling microscopy was used to study the (bi)carbonate adsorption on Cu(100) in 0.1 M KHCO3. Different ordered adlayer phases with (2√2 x 6 2√2)R45 degrees and (4x4) unit cells were found in the double layer potential regime. The adlayer consists of coadsorbed carbonate and water molecules and undergoes a reversible order-disorder phase transition at 0 V vs. the reversible hydrogen electrode, which is strongly stabilized by liquid water in the adjacent electrolyte.

Hydrogen-Induced Restructuring of a Cu(100) Electrode in Electroreduction Conditions

Zisheng Zhang et al.

Summary: Atomistic insight into the restructuring of the electrochemical interface under different potentials and adsorbate coverages is gained from first principles. The study reveals the formation of a shifted-row reconstruction on Cu(100) under electroreduction conditions induced by hydrogen adsorption. The findings provide valuable understanding for the design of Cu-based materials in electrocatalysis.

The nature of active sites for carbon dioxide electroreduction over oxide-derived copper catalysts

Dongfang Cheng et al.

Summary: This study reveals the active sites for CO2 electroreduction over oxide-derived copper (OD-Cu) catalysts, identifying square-like sites responsible for specific products. Planar and convex square sites are found to be responsible for ethylene production, while the step square site favors alcohols generation, providing fundamental insights into the origin of activity and selectivity over Cu-based catalysts.

Surface Hydride Formation on Cu(111) and Its Decomposition to Form H2 in Acid Electrolytes

Brian M. Tackett et al.

Summary: The study reveals that on Cu(111) surface, the redox wave of hydride formation coincides with anion desorption, and the reverse reaction yields H-2 instead of H3O+. Additionally, two-dimensional hydride formation can be characterized through reduction wave and specific vibrational bands.

Modeling Potential-Dependent Electrochemical Activation Barriers: Revisiting the Alkaline Hydrogen Evolution Reaction

Jiang Li et al.

Summary: Accurate theoretical simulation of electrochemical activation barriers is crucial for understanding electrocatalysis. By developing an analytical approach based on charge conservation and decoupled potential energy surfaces, we successfully simulated the Pt-catalyzed alkaline hydrogen evolution reaction with consideration of solvent thermal fluctuations, showing the significant impact of water-metal distances on charge transfer barriers.

Dynamic transformation of cubic copper catalysts during CO2 electroreduction and its impact on catalytic selectivity

Philipp Grosse et al.

Summary: To design effective and stable catalysts for energy conversion applications, it is essential to understand how they transform under reaction conditions and reveal the structure-property relationships, especially for catalysts used in the electroreduction of carbon dioxide. Real-time electrochemical studies show the restructuring of copper(I) oxide cubes during reaction and its impact on catalyst selectivity. Understanding the changes in catalysts during reaction is crucial for rational design, with studies linking structural transformations of cubic copper oxide catalysts with their selectivity.

Efficient CO2 electroreduction on facet-selective copper films with high conversion rate

Gong Zhang et al.

Summary: The authors developed a novel synthetic approach to prepare Cu(100)-rich thin film electrodes for CO2 electroreduction, achieving high Faradaic efficiency for ethylene and C2+ products. Scaling up the electrode led to increased total current and higher yield of desired C2+ products. Insights into Cu facets exposure effects on intermediates were provided through in situ spectroscopic methods and theoretical calculations, enabling precise design of CO2 reduction reactions for future industrial applications.
