Fig. 3

UV-Vis absorption spectra of Indigo Carmine solutions at various vibration time for the a poled and b unpoled BTO nanoparticles. The inset in each Figure is a series of photographs of a piezo-catalyzed Indigo Carmine dye solution time progression from left to right. Piezo-catalytic degradation efficiency performance of the poled and unpoled BTO nanoparticles in c direct concentration ratio C/C0 and d logarithmic relationship of ln(C0/C) by fitting with a linear function. e Electron paramagnetic resonance spectra (EPR) of radical spin-trapped by 5,5-dimethyl-1-pyrroline N-oxide (DMPO) over different piezo-catalysts in aqueous dispersion (top) and dimethyl sulfoxide (DMSO) dispersion (bottom).
