摘要

压电增强光催化剂用于污染物降解是环境保护领域的一种创新方法。本文将熔融盐法合成的Bi5Ti3FeO15 （BTFO）微晶片状催化剂应用于污染物降解，该催化剂通过耦合压电和光多场效应实现了协同增强的催化性能。其独特的单晶结构、片状形态、窄带隙能和压电辅助等因素使其具有较强的催化性能。在超声激励应用过程中，压电内建电场加速了载流子的分离和迁移。本研究为利用多场耦合效应制备高效催化剂提供了一种可行的策略。

Enhanced piezo-photocatalytic performance in Bi5Ti3FeO15 micro-crystalline platelets synthesized by a molten-salt method

The piezoelectric enhancement technology for photocatalysts used in pollutant degradation is an innovative approach in the field of environmental protection. In this paper, Bi₅Ti₃FeO₁₅ (BTFO) micro-crystalline platelets catalysts synthesized by a molten-salt method were applied for pollutant degradation, which can achieve a synergistic enhanced catalytic performance by coupling the piezo- and photo- multi-field effects. The enhanced catalytic performance of BTFO platelets stems from its unique single-crystal structure, sheet-like morphology, narrow bandgap energy and piezoelectric assistance. The piezo-induced build-in electric field accelerates the carrier separation and migration during the application of ultrasound excitation. This work provides a feasible strategy in the preparation of efficient catalysts by utilizing multi-field coupling effects.
