A new study explores the distinct roles of spontaneous polarization and piezoelectric in piezo-phototronic coupling. This investigation focuses on differences photocatalytic piezo-photocatalytic performance using sodium bismuth titanate, a key ferroelectric material. The research aims to identify which type has greater influence effects. theoretical assessment complements experimental findings, providing additional insights. enhanced electrospun nanofibers compared sol-gel particles under different illumination conditions (11 W UV, 250 natural sunlight). Electrospun exhibited rate constant (k) improvement 2.5 3.75 times, whereas showed only 1.3 1.4 times higher when ultrasonication was added photocatalysis. Analysis first-principle methods revealed that had an elastic modulus (C33) about 2.15 lower than particles, indicating flexibility. elongation lattice along z axis case reduced covalency Bi-O Ti-O bonds. These structural stress coefficients (e31 e33). Despite having coefficients, flexibility led strain coefficient, 2.66 1.97 respectively. improved coupling for nanofibers.
