Abstract

= 0.992). Photoluminescence (PL) quenching, radical scavenger experiments, and reduced charge transfer resistance from electrochemical impedance spectroscopy (EIS) collectively indicate improved charge separation and suppressed recombination in the co-doped system. Furthermore, the photocatalyst retained its structural integrity and photocatalytic efficiency over five consecutive cycles, as confirmed by post-reaction XRD analysis. These findings demonstrate that synergistic Cu/Sr co-doping effectively tuned the structure-property-performance relationship in ZnO, leading to enhanced and stable photocatalytic activity.
