Piezo-catalysis induced by piezoelectric polarization has been proven to be a powerful technology for potential applications in the energy and environment. It is generally accepted that piezo-catalysis derived the easily deformation from the piezoelectric materials with one or two dimensions. In this study, piezoelectric materials lead zirconate titanate (PZT) with a spherical morphology was synthesized, which is used to explore whether the widely accepted principle that is one or two-dimensional structure is necessary in the piezo-catalysis process is exclusive. We would like to clarify the relationship between deformation and piezoelectric catalytic performance. In addition, a key fundamental problem that has not yet been fully solved whether the charges of the reaction are from polarized charges or free charges. We investigate the role of polarization charges and free charges in piezoelectric catalysis by doping the piezoelectric material. It is hoped that the study of this work will re-understand and explain the mechanism of piezoelectric catalytic reaction.

工程球形锆钛酸铅,探索压电催化的本质

压电极化引起的压电催化已被证明是一种在能源和环境中潜在应用的强大技术。通常接受的是,压电催化容易地从具有一维或二维的压电材料中产生变形。在这项研究中,合成了具有球形形态的压电材料钛酸锆钛酸铅(PZT),用于研究压电催化过程中是否需要广泛接受的一维或二维结构原理。我们想澄清变形与压电催化性能之间的关系。另外,该反应的电荷是来自极化电荷还是来自自由电荷,还没有完全解决一个关键的基本问题。我们通过掺杂压电材料来研究极化电荷和自由电荷在压电催化中的作用。希望对这项工作的研究能够重新理解和解释压电催化反应的机理。
