Summary
Researchers constructed a piezoelectric self-Fenton system using iron-doped tin disulfide that uses mechanical vibrations to generate reactive radicals capable of breaking down organic water pollutants, achieving complete degradation of a model dye pollutant while also reducing its toxicity. This combination of two degradation mechanisms in a single material offers a promising energy-efficient approach for cleaning contaminated water without external chemicals.
Abstract Both piezoelectricity and self-Fenton catalysis are effective ways to degrade water pollution, but little research has combined them to construct a more efficient water pollution treatment method. Here, a Fe-doped SnS 2 (Sn 1-x Fe x S 2 ) piezoelectric self-Fenton system was constructed, which shows superior water treatment performance. The best piezoelectric properties of the Sn 0.97 Fe 0.03 S 2 system were verified by degrading rhodamine B (RhB). The toxicity analysis of degradation intermediates and solutions confirmed that the toxicity of RhB decreased after degradation. In addition, Kelvin probe force microscopy and photoelectrochemical analysis confirmed the better piezoelectric properties of Sn 0.97 Fe 0.03 S 2 . It has demonstrated the enhancement of systematic piezoelectricity by Fe lattice defects and the formation of self-Fenton by Fe as an active center in the degradation of RhB. In this work, an efficient piezoelectric and self-Fenton technology is constructed to remove organic pollutants from water, which is significant for developing water treatment technology.
