Published: Jan. 15, 2025

Electricity-powered C─C coupling of CO2 represents an attractive strategy for producing valuable commodity chemicals with renewable energy, but it is still challenging to gain high C2+ selectivity at current density. Here, a Sn1Cu single-atom alloy (SAA) reported isolated Sn atom embedded into the Cu lattice, as efficient ectrocatalyst reduction. The prepared Sn1Cu-SAA catalyst shows maximal Faradaic efficiency 79.3% 800 mA cm-2, which can be kept stable least 16 h. combination in situ spectroscopy and DFT calculation reveal that introduced promote activation *CO, enhance CO coverage on Sn1Cu-SAA. As results, reaction barrier pathway significantly reduced, boosting generation products. These findings offer novel sight fabricating multicarbon products from via regulation concentration intermediates catalytic interface.

Engineering Flow‐Through Hollow Fiber Gas‐Diffusion Electrodes for Unlocking High‐Rate Gas‐Phase Electrochemical Conversion

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 6, 2025

Abstract Designing advanced electrodes with efficient contact gas, electrolytes, and catalysts presents significant opportunities to enhance the accessibility of concentrated gas molecules catalytic sites while mitigating undesirable side reactions such as hydrogen evolution reaction (HER), which advances gas‐phase electrochemical reduction toward industrial‐scale applications. Traditional planar face challenges, including limited solubility restricted mass transport. Although commercial flow‐by gas‐diffusion can reduce transfer resistance by enabling direct diffusion active sites, reliance on diffusive flow becomes insufficient meet rapid consumption demands reactants at high current density. Flow‐through hollow fiber (HFGDEs) or penetration (HFGPEs) provide a promising solution continuously delivering convective resulting in enhanced transport superior near sites. Notably, HFGDEs have demonstrated ability achieve densities exceeding multiple amperes per square centimeter liquid electrolytes. This review provides comprehensive overview design criteria, fabrication methods, strategies for porous metallic HFGDEs. It highlights state‐of‐the‐art advancements composed various metals (e.g., Cu, Ni, Ag, Bi, Ti, Zn), particular focus their utilization conversion CO 2 . Finally, future research directions are discussed, underscoring potential versatile scalable electrode architecture diverse

Amino‐Induced CO₂ Spillover to Boost the Electrochemical Reduction Activity of CdS for CO Production

Small, Journal Year: 2024, Volume and Issue: unknown

Published: June 8, 2024

Abstract A considerable challenge in CO 2 reduction reaction (CO RR) to produce high‐value‐added chemicals comes from the adsorption and activation of form intermediates. Herein, an amino‐induced spillover strategy aimed at significantly enhancing capabilities CdS supported on N‐doped mesoporous hollow carbon sphere (NH −CdS/NMHCS) for highly efficient RR is presented. The prepared NH −CdS/NMHCS exhibits a high Faradaic efficiency (FE ) exceeding 90% −0.8 −1.1 V versus reversible hydrogen electrode (RHE) with highest FE 95% −0.9 RHE H cell. Additional experimental theoretical investigations demonstrate that alkaline −NH group functions as potent trapping site, effectively adsorbing acidic , subsequently triggering CdS. amino modification‐induced spillover, combined electron redistribution between NMHCS, not only readily achieves spontaneous * COOH but also greatly reduces energy required conversion intermediate, thus endowing improved kinetics reduced overpotential ‐to‐CO conversion. It believed this research can provide valuable insights into development electrocatalysts superior application.
