摘要：The piezoelectric effect presents a promising avenue for harvesting and utilizing low-grade mechanical energy. However, challenges from lacking matched industrial equipment and maintaining catalytic performance during scaling up impede the engineering of piezo-catalysis. Here, utilizing mechanical energy of water to inspire piezoelectricity, a successful attempt at large-scale piezo-catalysis seawater H-2 evolution was reported for the first time, exhibiting an efficiency of 36.82% for converting mechanical energy to hydrogen energy. A scaling-up test with 20 L of seawater was conducted, yielding an H-2 production rate of 0.73 L h(-1), which just occupied 0.7 m(2). This performance (1.04 L h(-1) m(-2)) exceeds the large-scale photocatalytic pure water H-2 production by panel reactor array (0.18 similar to 0.25 L h(-1) m(-2)) reported in 2021. Additionally, the H-2 evolution activity of the 20 L system showed no obvious decline compared with the 50 mL system before scaling-up, owing to the utilization of ternary piezo-catalysts system, which capitalized on the synergistic coupling effect of kinetics and thermodynamics. This attempt provides a prototype for pursuing large-scale piezo-catalysis and practical engineering application.
