In this work, a novel FeNi2S4/TiO2–x nanocomposite was prepared by facile hydrothermal synthesis, then comprehensively characterized by a multitechnique approach, and subsequently employed for round-the-clock (light and dark) removal of rhodamine B. Superior improvement of the morphological and thermal properties of the FeNi2S4/TiO2–x nanocomposite due to the use of sodium dodecyl sulfate was investigated. An l-ascorbic acid-assisted photo-Fenton catalyst can be employed effectively for complete rhodamine B removal at 30 min using a 10 W white-light-emitting diode (LED) source under a wide range of operating conditions compared to other reported photo-Fenton catalysts. The obtained results show a significant synergism between the nanocomposite components, which makes the total RhB removal much better than when each was used alone. This study presents a facile approach to designing a sustainable multifunctional catalyst with reusability, high catalytic activity, and environmental friendliness. Due to the photocatalytic and photo-Fenton synergism in the presence of hydrogen peroxide and ascorbic acid under visible light, there is high potential to generate more electron/hole carriers and hydroxyl radicals (•OH).

“…In other words, it lowers the conduction band (CB) of the piezo material to below the highest occupied molecular orbital (HOMO) of the molecule of piezo material. Therefore, the electrons could transfer from the HOMOs of molecules to the CB of piezo material 13 – 17 . In the past, piezo materials mainly were used as sensors, transducers, and electronic industries 18 – 20 .…”

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.

“…During the process of piezocatalysis, the polarization electric field originating from the deformation of piezoelectrical materials could provide a driving force to promote the migration and separation of two types of carriers in opposite directions to participate in the oxidation reduction reaction. [1][2][3][4][5][6] In recent years, piezocatalysis has garnered considerable attention from researchers, being widely used in hydrogen generation, [7][8][9] pollutant degradation, [10][11][12] tumor therapy, 13 reactive oxygen species evolution (ROS), 14 etc. However, in these piezocatalysis applications, the mechanical energy is mainly low frequency vibration, so it takes tens of microseconds for piezoelectric materials to generate piezoelectric fields in different directions.…”
