“…The prominent peak of TC is at m / Z = 445. In general, functional groups such as double bonds, amine, and phenolic groups are degraded due to their relatively high electron density, out of which double bonds have higher reactivity than others and therefore readily undergo hydroxylation to produce primary product 2 ( m / Z = 467) [ 88 ]. Due to the weak binding energy of N-C, product 3 ( m / Z = 381) and product 4 ( m / Z = 359) are obtained by N-demethylation and deamidation.…”

Multifunctional core@shell nanoparticles have been synthesized in this paper through 3 stages: NiFe2O4 nanoparticles by microwave irradiation using Pedalium murex leaf extract as a fuel, core@shell NiFe2O4@TiO2 nanoparticles by sol-gel, and NiFe2O4@TiO2@rGO by sol-gel using preprepared reduced graphene oxide obtained by modified Hummer’s method. XRD analysis confirmed the presence of both cubic NiFe2O4 spinel and tetragonal TiO2 rutile phases, while Raman spectroscopy analysis displays both D and G bands (ID/IG = 1.04) associated with rGO. Morphological observations by HRTEM reveal a core-shell nanostructure formed by NiFe2O4 core as confirmed by SAED with subsequent thin layers of TiO2 and rGO. Magnetic measurements show a ferromagnetic behavior, where the saturation magnetization drops drastically from 45 emu/g for NiFe2O4 to 15 emu/g after TiO2 and rGO nonmagnetic bilayers coating. The as-fabricated multifunctional core@shell nanostructures demonstrate tunable self-heating characteristics: rise of temperature and specific absorption rate in the range of ΔT = 3–10°C and SAR = 3–58 W/g, respectively. This effectiveness is much close to the threshold temperature of hyperthermia (45°C), and the zones of inhibition show the better effective antibacterial activity of NTG against various Gram-positive and Gram-negative bacterial strains besides simultaneous good efficient, stable, and removable sonophotocatalyst toward the TC degradation.

“…The piezocatalytic degradation of organic pollutants has been demonstrated by various nano-piezocatalysts, such as ZnO, BaTiO 3 , Bi 5 Ti 3 FeO 15 , , g-C 3 N 4 , , (1 – x )Pb(Mg 1/3 Nb 2/3 )O 3 – x PbTiO 3 , , MoS 2 , and so on. The intrinsic factors of nano-piezocatalysts, including piezoelectric coefficient, surface area, and oxygen vacancy, have positive effects on piezocatalytic performance. − However, the nano-piezocatalysts with the above characteristics usually need expensive raw materials and a time-consuming synthesis process.…”

Piezocatalysis is an emerging and promising catalytic technique for degrading organic pollutants by harvesting mechanical energy. However, the catalytic efficiency and environment compatibility of present piezocatalysts are still unsatisfactory. Here, the superior piezocatalytic performance of eco-friendly poly(tetrafluoroethylene) (PTFE) micron powders was demonstrated by degrading several typical dyes. Methylene blue can be degraded by 99% within 20 min (k = 0.246 min–1) using fresh PTFE under ultrasonic vibration, and PTFE exhibits excellent stability and reusability. In addition, rhodamine B, acid orange 7, and methyl orange can also be degraded by 100, 98, and 99% within 60 min, respectively, demonstrating the wide adaptability of PTFE. Catalytic mechanism investigations demonstrate that •OH and •O2 – play major roles in dye degradation. Furthermore, the influence of various water sources and different containers on the catalytic performances of PTFE was explored, indicating that PTFE has nice environmental suitability and that the glass container facilitates catalytic degradation. Therefore, a designed glass spiral tube was applied for large-volume wastewater purification, which can be further extended for potential applications. This work thus demonstrates that PTFE can be regarded as a promising catalyst for wastewater treatment by harvesting mechanical energy, and the proposed Z-shaped wastewater degradation device has potential applications in wastewater treatment.
