Stimulated piezotronical decontamination using Cu₂MgSnS₄ modified BaTiO₃

Water resources are drastically decreasing due to the aquatic pollutants involved with the rapid growth of microbial colonies. Mitigation of contaminants and corresponding actions is necessary to impede severe health risks and fulfill clean water demand. Piezocatalysis appears as a potential advanced oxidation technique based on vibrational energy harvesting mechanism and conversion with piezo materials’ assistance. Owing to the effectiveness of piezocatalysis, we synthesized the Cu₂MgSnS₄ modified BaTiO₃ (CMTS@BTO) displayed remarkable piezocatalytic degradation against organic contaminants and microbes. CMTS@BTO revealed more than 90% disinfection in heterotrophic conditions while also degraded 88–98% of organic dyes using ultrasound vibrations. Our findings have a significant contribution to water remediation and indicate potential use in other biological applications.
