Abstract

sites. This structural evolution causes a negative shift in the conduction band potential, impedes charge separation, and increases the reaction barrier, leading to a noticeable loss in activity over cycles. This work underscores the pivotal role of maintaining isolated metal sites for designing stable and efficient MOF-based photocatalysts for nitrogen cycling.
