Summary: Electrochemical CO2 reduction (CO2R) is a method to close the carbon cycle for chemical synthesis. The research has mainly focused on ambient pressure CO2, but industrial CO2 is usually pressurized and in dissolved form. By studying the effects of pressure on CO2R, the researchers found that higher pressure leads to increased formate selectivity. They further enhanced this pressure-mediated effect by functionalizing the surface of a Cu cathode with a proton-resistant layer. This work highlights the potential of using industrial CO2 as a feedstock for sustainable chemical synthesis.

Summary: We systematically studied the influence of p-block atom X (X = C, N, O, S, and Se) on CO2 catalytic properties on a Sn(200) surface and found that the p-block atoms have unique effects on CO2 electrocatalytic activity and product selectivity. In particular, the p-block C atom showed bi-functional activity while the p-block S(Se) atom exhibited strong selectivity towards HCOOH formation. These findings provide valuable insights for the design of highly efficient CO2 electrocatalysts.

Summary: Electrochemical reduction of nitrate to ammonia (NH3) offers a promising strategy for green NH3 synthesis and balances the perturbed nitrogen cycle. However, current electrocatalytic nitrate reduction processes are still inefficient due to the lack of effective electrocatalysts. In this study, 3D nanoporous Cu/MnOx hybrids were reported as efficient and durable electrocatalysts for nitrate reduction reaction, achieving high NH3 yield rates and Faradic efficiency. The interface effect between Cu/MnOx interface was found to enhance the catalytic activity and selectivity. This work provides an approach to design advanced materials for NH3 production via electrochemical nitrate reduction.

Summary: Electrocatalytic reduction of CO2 has been considered a promising pathway for carbon neutrality. Although considerable catalytic activity has been achieved in alkaline or near-neutral mediums, the formation of carbonates from the reaction between CO2 molecules and hydroxide ions leads to low energy efficiency and carbon utilization. Electrolysis of CO2 in acidic medium provides a viable alternative with high carbon utilization and low overpotential for anodic oxygen evolution reaction. This article discusses the progress in efficient CO2 electroreduction in acidic medium, including the discovery of cations' actions, rational design of electrode/catalysts, and local pH effect. The future development of efficient acidic CO2 electrolysis, focusing on catalyst/electrode design and catalytic microenvironment optimization to enhance the selectivity of C-C coupling, is also discussed.

Summary: The traditional method for synthesizing NH3 is inefficient and causes pollution, while electrochemical synthesis through nitrate reduction is a promising alternative. A new Au/Cu catalyst is introduced for nitrate reduction to NH3, which demonstrates high yield rate and Faradaic efficiency. Unlike other catalysts, Au/Cu exhibits better activity for nitrate reduction than nitrite reduction due to enhanced adsorption capabilities and lower energy barriers.
