Summary: The electrocatalytic CO2 reduction reaction (CO2RR) to C2+ products is of great importance. The co-operation of Cu1+ and Cu-0 in the catalysts can yield a high faradaic efficiency (FE), but it is difficult to determine the optimal ratio of Cu1+ and Cu-0. In this study, a strategy to prepare Cu catalysts with different oxidation states, stabilized by the pulsed electrolysis method during CO2RR, was proposed. It was found that Cu catalyst with an oxidation state of +0.41 exhibited the highest efficiency, with a FE of C2+ products at 70.3% in an H-type cell. This work provides a precise method to identify the optimal oxidation state of unstable catalysts in the reaction.

Summary: Developing alternative electrolysis techniques is crucial for advancing electrocatalysis. Recent studies have shown that pulse electrochemical CO2 reduction reaction (CO2RR) can improve the selectivity of CO2RR. This study reveals that pulse electrolysis improves the C(2+) selectivity of CO2RR through dynamic controls of the surface CuxO/Cu composition.

Summary: Increasing the surface availability for CO(2) by using cation-exchange ionomers can enhance the C(2+) product formation rates in Cu-catalyzed electrochemical CO(2) reduction reaction (CO2RR). However, it also shortens the residence of *CO, leading to lower C(2+) selectivity. This study discovers that using quaternary ammonium group-functionalized hydrophobic polynorbornene ionomers can prolong the *CO residence time on Cu, resulting in significantly improved C(2+) Faradaic efficiencies.

Summary: This review focuses on Cu-based catalysts for the electrochemical CO2 reduction reaction (CO2RR) to produce high-value-added C2+ products. The rational design of Cu-based catalysts is crucial to enhance the selectivity and energy efficiency of the CO2RR-to-C2+ process. Recent advances in surface-modified Cu-based catalysts are discussed, including surface hydrophobization, CO2-capture materials, halide-ion doping, and confinement structures. The relationships between surface properties and improved activity and selectivity, as well as strategies for enhancing catalyst stability, are also discussed. The challenges and potential strategies for future CO2RR-to-C2+ research are highlighted.

Summary: CO2 electrolysis is a sustainable technology that can accelerate global decarbonization by producing high-value alternatives to fossil-derived products. Single-component catalysts often face limitations in achieving high selectivity due to the competitive formation of C-1 products, but tandem catalysis can overcome these limitations by incorporating a component that generates a high concentration of CO, the primary reactant involved in forming C2+ products. Various approaches to promote tandem CO2 electrolysis have been proposed, ranging from atomic-scale manipulation to device-scale engineering.

Summary: This study proposes a simple method to construct a graphdiyne (GDY) supported Ag-Cu nanocluster as a selective electrocatalyst for producing C2+ products. Compared to Cu/GDY, the Ag-Cu/GDY tandem scheme exhibits superior performance in CO2RR to C2+ products. Theoretical calculations show that CO has a higher adsorption energy on Cu than on Ag, promoting the drift of *CO from Ag to Cu. Additionally, the key C-C coupling reaction of *CO with *COH is more favored on Ag-Cu/GDY, contributing to the formation of C2+ products.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: This study systematically investigates the key roles of Nafion on Cu nanoparticles electrocatalyst for CO2RR. The Nafion modifier suppresses the hydrogen evolution reaction, increases CO2 concentration and mass transfer process, and activates CO2 molecule to enhance C2 product generation. As a result, the selectivity of the hydrogen evolution reaction is reduced and the efficiency of C2 products is significantly improved.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
