Atomic-Level Charge Engineering for Efficient CO₂ Electroreduction 🔋🌿
Cu/Ni dual-atom catalysts with charge regulation: Boosting CO₂ electroreduction selectivity via site-specific O/C-terminal asymmetric adsorption is an exciting breakthrough in electrocatalysis and carbon-neutral energy research 🌍⚡. Scientists designed a Cu/Ni dual-atom catalyst anchored on N-doped carbon that enhances the electrochemical CO₂ reduction reaction (CO₂RR) by regulating electronic interactions between copper and nickel atoms. Unlike conventional single-atom catalysts, the synergistic interaction between Cu and Ni redistributes charge density, enabling selective adsorption of CO₂ intermediates and dramatically improving catalytic efficiency. This strategy supports the conversion of greenhouse CO₂ into valuable chemicals like CO with significantly higher selectivity and stability 🚀. A key innovation of this catalyst lies in its site-specific asymmetric adsorption mechanism 🔬. Electron-deficient Cu atoms preferentially bind oxygen terminals of CO₂, ...
