“…The kinetics of degradation and characteristic constants of degradation by piezocatalyst can be studied through kinetic measurements using pseudo-first-order, pseudo-second-order, and intra-particle diffusion. The Lagergren pseudo-first-order model is given as follows 43 , 44 : where q e and q t (mg g 1 ) are the amounts of the MB degraded at equilibrium and at time t (min). k 1 (min −1 ) is the rate constant.…”

Mechanical energy harvesting by piezoelectric materials to drive catalysis reactions received extensive attention for environmental remediation. In this work, SbSI/Sb2S3 nanocomposites were synthesized as a catalyst. ZrO2 balls were used as an alternative mechanical force to ultrasonic for stimulating the piezocatalyst for the first time. The kinetics and thermodynamics of the piezo degradation of methylene blue (MB) were studied deeply. Besides the effect of the type of mechanical force, the number of ZrO2 balls, and temperature of the reaction on the degradation efficiency were studied. Here mechanical energy came from the collision of the ZrO2 balls with the catalyst particles. Using ZrO2 balls instead of ultrasonic vibration led to enhance degradation efficiency by 47% at 30 ± 5 °C. A kinetic study revealed that piezo degradation of methylene blue (MB) by SbSI/Sb2S3 catalyst followed pseudo-second-order kinetics. Based on thermodynamic results piezo degradation of MB was an exothermic reaction.

requirements of functionality and stabilization at high-temperature conditions. [5][6][7] Ferroelectric ceramics with the perovskite structure ABO 3 , such as BaTiO 3 , Pb(Zr,Ti)O 3 , and Pb(Mg 1/3 Nb 2/3 ) O 3 -PbTiO 3 , usually possess high piezoelectric constants d 33 (100-1500 pC N −1 ), but their Curie temperature T c is low (50-400 °C). [8,9] Thus, the usage range of the system is restricted to below 300 °C. Bismuth layer-structured ferroelectrics (BLSFs) have the general chemical formula (Bi 2 O 2 ) 2+ (A m-1 B m O 3m+1 ) 2− , and their structure is that (A m-1 B m O 3m+1 ) 2− perovskite layers are sandwiched between (Bi 2 O 2 ) 2+ fluorite-like layers along the c-axis. [10] Consequently, BLSFs piezoelectrics possess high Curie temperature T c (500-1000 °C), high mechanical quality factors, and low aging rates, which make them promising candidates for the hightemperature electronic industry. [11][12][13] Bismuth titanate, Bi 4 Ti 3 O 12 (BIT), is always regarded as an excellent candidate for high-temperature electromechanical systems owing to its high Curie temperature (T c is of 675 °C) as well as outbound spontaneous polarization (P s is of 50 µC cm −2 along the a-axis). [14][15][16] However, the piezoelectricity of BIT ceramics is poor (only 6-8 pC N −1 ) due to its strong anisotropic polarization, a large coercive field, and high leakage current. Extensive research has been made to acquire high-performance BITbased ceramics, including chemical modification and grain orientation techniques. [17][18][19][20][21][22][23] For example, a high d 33 of 21 pC N −1 and T c of 655 °C, as well as a lower dielectric loss of 0.3%, High-temperature piezoelectric materials are widely needed in electromechanical sensors, actuators, and transducers that are exposed to high-temperature conditions. Bismuth layer-structured bismuth titanate (Bi 4 Ti 3 O 12 , BIT) ferroelectrics have a high Curie temperature of 675 °C but suffer from poor electrical properties, especially the piezoelectricity. Here, a giant piezoelectric coefficient d 33 of 40.2 pC N −1 is obtained in the Bi 3.97 Ce 0.03 Ti 2.98 (WNb) 0.01 O 12 ceramics with a high Curie temperature of 657 °C, the highest value reported to date in BIT-based piezoceramics. Electrical property and microstructural analysis reveal that the high piezoelectricity benefits from the preferential orientation of ferroelectric domains, the irreversibility of ferroelectric domain reorientation, and the high density of ferroelectric domain walls. Besides, excellent thermal stability of piezoelectric constant (d 33 = 36.7 pC N −1 at 500 °C, <10% variations in the range of room temperature to 500 °C), high electrical resistivity (ρ > 10 7 Ω cm at 500 °C), and low loss (tanδ < 1.5% at 500 °C) are also obtained in the Bi 3.97 Ce 0.03 Ti 2.98 (WNb) 0.01 O 12 ceramics. This work not only penetrates the origins of outstanding piezoelectricity of BITbased ceramics but also offers prospects for brand-new tactics to exploit high-performance high-temperature piezoceramics.
