Enhancing Flexoelectric Catalytic Performance by Modulating the Intrinsic Magnetism of LaCrO 3

Abstract Flexoelectric catalysis is an emerging catalytic strategy that enhances catalytic performance through the flexoelectric polarization effect generated by materials subjected to non‐uniform strain. This study proposes, for the first time, a strategy to enhance the efficiency of flexoelectric catalysis and improve the selectivity of products by modulating the intrinsic magnetism of the catalyst. The transition from the paramagnetic (PM) to the antiferromagnetic (AFM) state in LaCrO 3 significantly enhances the flexoelectric polarization effect and boosts hydrogen peroxide production rate by 90%. Importantly, the AFM state of the LaCrO 3 catalyst exhibits weaker oxygen adsorption and more restricted electron transfer compared to the PM state, inhibiting complete oxygen dissociation and the formation of highly reactive intermediates (hydroxyl and superoxide radicals), while improving the selectivity for the two‐electron oxygen reduction reaction pathway. This study underscores the significance of regulating the intrinsic magnetism of catalysts in flexoelectric catalysis and offers a novel idea for designing efficient and controllable flexoelectric catalysts.
