抄録	Piezocatalytic CO₂ reduction provides a promising route for converting CO₂ to value-added chemicals driven by ubiquitous mechanical energy. However, the efficiency of current piezocatalysts is limited by sluggish CO₂ adsorption in water, scarce active sites, and inefficient charge-transfer pathways. Herein, we demonstrate that coating barium titanate (BaTiO₃, BT) with a hydrophobic shell of a Cu single atom doped zeolitic imidazolate framework-8 (Cu-ZIF-8) facilitates piezocatalytic CO₂ reduction. Optimized Cu-ZIF-8/BT exhibited a CO yield of 114 μmol·g⁻¹·h⁻¹, approximately five-fold higher than that observed for pristine BT (24 μmol·g⁻¹·h⁻¹). Comprehensive analyses revealed that the Cu-ZIF-8 coating on BT enhanced piezocatalytic CO₂ reduction, which was due to the improved utilization of piezo-generated electrons, increased the interfacial availability of CO₂, and activated CO₂ by the hydrophobic CO₂-enriching shell containing atomically dispersed redox-active Cu centers. This work highlights a rational interfacial engineering strategy for designing piezocatalysts, offering insights into improved CO₂ conversion and the development of advanced piezocatalytic systems.
