Electrochemical conversion of CO₂ via C−X bond formation: recent progress and perspective

Chemical Synthesis, Journal Year: 2024, Volume and Issue: 4(4)

Published: Oct. 9, 2024

With the depletion of traditional energy sources and growing environmental concerns, it is becoming increasingly urgent to develop green, low-emission renewable technologies replace fossil fuel-driven methods that emit carbon dioxide (CO2). Currently, electrochemical production high-value-added chemicals fuels from CO2 has aroused great interest scientists. However, make full use for preparation chemicals, necessary expand range electrosynthesis methods, in particular by expanding reaction pathways through with different substrates. In general, can form new covalent bonds substrate molecules formation C−X bonds, including C−H, C−C, C−N, C−O, C−S which would possible products diversifying pathway. this review, we focus on research progress conversion bond formation. We start examining fundamentals reactions summarizing modes. Next, discuss (C−H, C−S) using molecules. Finally, (i) strategies design activity optimization catalyst materials (ii) future development forming five types small are discussed, along an outlook their prospects.

Published: Sept. 8, 2024

Herein, the effect of B elements on microstructure and catalytic properties Cu–31.5Fe–4.5P immiscible alloy is systematically investigated. After characterizations, it found that are mainly concentrated in Fe x P (Fe 2 P, 3 P) particles, which affect Marangoni motion particles. With concentration content increasing to 0.75%, diameter size second‐phase particles alloys first refined then coarsened, with 0.25% has finest particle proportion sizes ranging from 1 10 μm reaches 97%. The electrochemical characterization dealloyed specimens shows overpotential Cu–Fe–P containing 193 mV at a current density mA cm −2 0.5 m H SO 4 solution. excellent performance might be attributed increase obviously specific surface area significant electron transfer.

Abstract Electrocatalytic formaldehyde oxidation with metal Cu electrocatalyst has attracted significant interest since it can produce H 2 at the anode and make possible to construct a bipolar hydrogen production cell low voltage. However, activity of will be greatly weakened after oxidizing + or 2+ . Here, CuFe bimetallic catalyst is developed efficiently catalyze electro‐oxidation process HCHO potential 0.10 V RHE current density 100 mA cm −2 It confirmed that introducing Fe in regulate electron configuration prevent 0 improve stability catalysts. The introduction reduce energy barrier reaction process, C─H bond more easily split on CuFe. A device constructed by combining anodic cathodic evolution. 500 achieved voltage 0.6 V. faradaic efficiency ≈100% stable for ≈50 h. research provides promising path toward secure, effective, expandable generation high‐purity both electrodes.
