In a major advancement toward carbon neutrality, researchers from Tohoku University, Tokyo University of Science, and Vanderbilt University have developed an atomically precise copper nanocluster that offers high stability and remarkable selectivity for electrochemical Carbon dioxide reduction. Published in JACS on June 26, 2025, the study introduces a unique Copper cluster featuring a single Copper atom within a Copper framework an innovation that significantly enhances catalytic performance.

This subtle atomic tweak reshapes the cluster’s electronic structure, improving its ability to convert Carbon dioxide into valuable products. the nanocluster achieved 26% Faradaic efficiency for formic acid and  for carbon monoxide, showing a clear preference for the more useful product.

DFT calculations revealed that the embedded Copper atom, though buried, alters surface activity by stabilizing key intermediates, notably formate ion, essential for formic acid formation. The cluster also demonstrated impressive post reaction stability.

This work highlights a powerful new approach for designing efficient, earth abundant electrocatalysts paving the way for smarter Carbon dioxide conversion strategies and sustainable chemical production.
