Abstract

Abstract: 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 Cu2 MgSnS4 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. Graphical abstract: Image 1 Highlights: Enhanced carrier generation was grasped by careful selection of P-type material to construct a p-n junction. Space charge layer at the interface solved fundamental problems of carrier recombination. Heterotrophic relation of organic contaminants with water bacterium explored. It evidenced that organic compounds have a significant influence on bacterial growth. CMTS@BTO achieved efficient disinfection percentages in heterotrophic conditions.
