Spin polarization induced by atomic strain of MBene promotes the ·O₂^- production for groundwater disinfection.

ABSTRACT: Superbugs in groundwater are posing severe health risks through waterborne pathways. An emerging approach for green disinfection lies at photocatalysis, which levers the locally generated superoxide radical (·O₂^-) for neutralization. However, the spin-forbidden feature of O₂ hinders the photocatalytic generation of active ·O₂^-, and thus greatly limited the disinfection efficiency, especially for real groundwater with a low dissolved oxygen (DO) concentration. Herein, we report a class of strained Mo_4/3B_2-xT_z MBene (MB) with enhanced adsorption/activation of molecular O₂ for photocatalytic disinfection, and find the strain induced spin polarization of In₂S₃/Mo_4/3
