Challenges related to energy shortages and environmental pollution are driving extensive research in catalysis. Flexocatalysis, which extends flexoelectricity mechanocatalysis, is a promising mechanism for catalytic processes. Owing its size-dependent effects, has become particularly significant plays dominant regulatory role chemical reactions within nanocatalysis. In this study, we integrated flexocatalysis with peroxymonosulfate (PMS) activation efficient water purification. The simulation results show that flexoelectric polarization can induce strong field δ-MnO2 nanosheets. This built-in electric subsequently drives the migration of electrons holes reaction interface, thereby activating PMS promoting rapid generation reactive species degradation organic pollutants. At low concentrations catalysts, achieved excellent efficiency was 6.6 times greater than obtained through thermal PMS. study demonstrated function as switch offers approach sustainable remediation.
