Abstract

High efficiency and stability are two crucial factors in piezocatalysis reactions. In this research, the efficiency of Fe₂O₃ piezo catalysts significantly increased by coupling it with Na₂WO₄. Results indicate that Fe₂O₃ and Na₂WO₄ have a synergetic effect on the degradation of Amoxicillin (AMX), with Fe₂O₃/Na₂WO₄ degrading 88 % of AMX in the same conditions that pure Fe₂O₃ and Na₂WO₄ degrade only 42 % and 20.6 %, respectively. The degradation efficiency of Fe₂O₃ was improved by 114 % when it was coupled with Na₂WO₄. Fe₂O₃/Na₂WO₄ piezo catalyst was successfully used in 8 cycles while it keeps almost 85 % of its efficiency which indicates the stability of prepared piezo catalysts. Studying the mechanism of degradation by Fe₂O₃/Na₂WO₄ revealed that superoxide free radicals have a critical function in the decomposition of AMX. The kinetic study also indicates that at lower temperatures, the reaction follows a first-order reaction.

Fe2O3 和 Na2WO4 压电催化剂去除水中药物废物的协同效应

高效和稳定是压电催化反应的两个关键因素。在这项研究中，Fe2O3 压电催化剂与 Na2WO4 的耦合使其效率显著提高。结果表明，Fe2O3 和 Na2WO4 对阿莫西林（AMX）的降解具有协同作用，在相同条件下，Fe2O3/Na2WO4 对 AMX 的降解率为 88%，而纯 Fe2O3 和 Na2WO4 对 AMX 的降解率分别只有 42% 和 20.6%。当 Fe2O3 与 Na2WO4 结合使用时，降解效率提高了 114%。Fe2O3/Na2WO4 压电催化剂成功使用了 8 个循环，其效率几乎保持在 85%，这表明所制备的压电催化剂非常稳定。对 Fe2O3/Na2WO4 降解机理的研究表明，超氧自由基在 AMX 的分解过程中起着关键作用。动力学研究还表明，在较低温度下，反应遵循一阶反应。
