Back Cover: Ternary Sn‐Ti‐O Electrocatalyst Boosts the Stability and Energy Efficiency of CO2 Reduction (Angew. Chem. Int. Ed. 31/2020)

3D ordered mesoporous materials used for electrochemical CO2‐to‐CO conversion offer potential ways to close the carbon loop and harvest renewable energies. In their Research Article on page 12860, Z. Bai, Z. Chen, and co‐workers show a trade‐off between active‐site exposure with structural stability and reveal an electron density reconfiguration at the Sn–Ti–O interface. The optimal nanostructured catalyst improves the half‐cell energy efficiency to over 70 % for 200 hours.
