A newly discovered nanometer material-mediated piezoelectrochemical (PZEC) for the direct conversion of mechanical energy to chemical energy has attracted increasing attention, for its great potential to be a green dye water decomposition technique. However, it is far from being a cost-effective and practical technique because only ultrasonic can be scavenged to decomposed organic pollutant in previous studies. Here, we prepared 0.5Ba(Zr_0.2Ti_0.8)O₃-0.5(Ba_0.7Ca_0.3)TiO₃ (BZT-BCT) piezoelectric fibers for the degradation of dye solution via slow stirring and studied the degradation mechanism. It provides a practical, green and low-cost method for decomposing organic dye by scavenging waste mechanical energy from the surrounding environment.

将机械能直接转化为化学能的新发现的纳米材料介导的压电电化学（PZEC）吸引了越来越多的关注，因为它具有绿色染料水分解技术的巨大潜力。但是，由于在先前的研究中只能将超声波清除为分解的有机污染物，因此它远不是一种具有成本效益的实用技术。在这里，我们制备了0.5Ba（Zr _0.2 Ti _0.8）O ₃ -0.5（Ba _0.7 Ca _0.3）TiO ₃（BZT-BCT）压电纤维通过缓慢搅拌降解染料溶液并研究了降解机理。它通过清除周围环境中的废机械能，为分解有机染料提供了一种实用，绿色且低成本的方法。
