Construction of piezoelectric photocatalyst Au/BiVO<sub>4</sub> for efficient degradation of tetracycline and studied at single-particle level

Figure 3. Catalytic degradation performance of TC over different samples. (A) Under ultrasonic stimulation; (B) Under visible light irradiation; (C) Catalytic degradation of TC under reaction conditions, both visible light and ultrasonic vibration; (D) The efficiency of ultrasound, photocatalysis, and both ultrasound and visible light irradiation in degrading TC for 60 min; (E) The rate constants k for TC degradation of BiVO₄ and xAu/BiVO₄; (F) The relationship between the degradation rate constant (k) of TC and absorption spectra of BiVO₄ and 3Au/BiVO₄ with different wavelengths. TC: Tetracycline; BiVO₄: bismuth vanadate.
