“Cu–N_x” Site-Driven Selectivity Switch for Electrocatalytic CO₂ Reduction

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 20, 2025

The comprehensive understanding of the effect chemical environment surrounding active sites on pathway for electrochemical carbon dioxide reduction reaction (eCO2RR) is essential development advanced catalysts large-scale applications. Based a series model engineered by coordination copper ions with various isomers phenylenediamine [i.e., o-phenylenediamine (oPD), m-phenylenediamine (mPD), and p-phenylenediamine (pPD)] featuring two amino groups in ortho-, meta-, para-positions, steric effects could significantly govern selectivity "Cu–N" eCO2RR. It was found distance between adjacent nitrogen Cu-oPD enhanced C–C coupling *COOH intermediate, thereby resulting increased C2H4 production. In contrast, weak van der Waals interactions arising from electrostatic *CHO intermediate Cu-pPD facilitated subsequent hydrogenation, leading to preferential synthesis CH4. However, Cu-mPD exhibited diminished eCO2RR activity due higher free energy associated rate-determining step, which primarily led formation H2. This study underscores significant role effect-driven switch

Rapidly Constructing Meter‐Scale Single‐Molecule Integrated Catalytic Electrode with Hydrophobic Microenvironment for pH‐Universal CO₂ Electroreduction

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

Published: March 21, 2025

Abstract The massive production of cost‐effective and highly‐efficient electrode materials is crucial for industrial CO 2 electroconversion. Herein, this work breaks away from conventional approaches by directly constructing an integrated single‐molecule catalytic (7F‐CoPc@GF) at the meter scale, through integration π‐extended macrocyclic structures into commercial carbon‐based collectors with strong interfacial interactions. This innovative method reshapes traditional design using a liquid‐phase self‐adaptive anchoring strategy, eliminating need conductive adducts binders. In addition, introducing perfluoroalkyl chain, built‐in hydrophobic microenvironment in heterogenized macrocycles optimizes electron migration water interaction around active sites, suppressing hydrogen evolution reaction thereby enhancing pH‐universal electroreduction across broad potential range. Significantly, mechanistic study reveals that not only enhances effective collisions between sites reactants but also facilitates immediate removal products surface. Further development dual value‐added electrolysis systems, incorporating waste gas treatment, highlights versatility extensibility meter‐scale material. These findings offer promising methodology rational stable, binder‐free, large‐size electrodes, advancing sustainable scale.
