Abstract The electrochemical reduction of CO 2 to form value‐added chemicals receives considerable attention in recent years. Copper (Cu) is recognized as the only element capable electro‐reducing into hydrocarbons with two or more carbon atoms (C 2+ ), but low product selectivity Cu‐based catalyst remains a major technological challenge overcome. Therefore, identification structural features catalysts great importance for highly selective production C products (ethylene, ethanol, n‐propanol, etc.), and oxidation state Cu species found critical performance. This review introduces efforts fine‐tune increase capture produce specific compounds, intention greatly expediting advance designs. It also points remaining challenges fruitful research directions development that can shape practical technology.

In current research, achieving carbon neutrality has become a primary focus through the utilization of various conversion technologies that transform dioxide (CO 2 ) into valuable chemicals or fuels. Covalent organic frameworks (COFs), as emerging crystalline polymers, offer distinct advantages in CO compared to other materials. These include controllable nanoscale pores, predefined functional units, editable framework structures, and rich conjugated systems. The unique characteristics COFs make them highly promising electrocatalysts for conversion. This review provides comprehensive overview pioneering works recent research on COF‐based materials electrochemical reduction reaction. offers analysis design principles reactive sites, skeleton pore functionalities, 3D frameworks, morphologies, composite COFs, aiming enhance electrocatalysis. Finally, this presents some recommendations material design, reaction mechanisms, theoretical computations understanding mechanisms further facilitate high‐performance electrocatalysts.

Abstract Electrochemical CO 2 reduction (ECR) to value-added products is regarded as a sustainable strategy mitigate global warming and energy crisis, designing highly efficient robust catalysts essential. In this work, transition metal sulfides (TMS)-decorated CuS microflower-like structures were prepared via the one-pot hydrothermal synthesis method for ECR CO, influence of TMS doping on performance was demonstrated. Characterization performed using XRD, FESEM-EDS, N physisorption, XPS, revealing successful loading TMS, formation architectures generation sulfur vacancies. tests demonstrated that ZnS, Bi S 3 , CdS MoS improved intrinsic activity catalyst. Particularly, -CuS composite catalyst with imperfect petal-like structure showed uniform distribution edge Mo sites, which worked synergistically formed grain boundaries (GBs) undercoordinated vacancy sites in promoting activation, stabilizing * COOH adsorption, facilitating desorption, lowering barrier potential-limiting step selectivity. The achieved maximum selectivity 83.2% at –0.6 V versus reversible hydrogen electrode (RHE) high cathodic energetic efficiency 100%. At potential, maintained stable catalytic during 333-min electrolysis process. findings will offer promising avenue development production from ECR.

Recent advances in nanoparticle materials can facilitate the electro-reduction of carbon dioxide (CO2) to form valuable products with high selectivity. Copper (Cu)-based electrodes are promising candidates drive efficient and selective CO2 reduction. However, application Cu-based chalcopyrite semiconductors electrocatalytic reduction is still limited. This study demonstrated that novel zinc oxide (ZnO)/copper indium gallium sulfide (CIGS)/indium (InS) heterojunction could be used effective for formic acid production. It has been determined Faradaic efficiencies production using ZnO nanowire (NW) nanoflower (NF) structures vary due structural morphological differences. A NW/CIGS/InS electrode resulted highest efficiency 77.2% 0.35 mA cm–2 current density at a −0.24 V (vs. reversible hydrogen electrode) bias potential. Adding ZTO intermediate layer by spray pyrolysis method decreased yield increased H2. Our work offers new via cost-effective scalable
