Piezo-photocatalysis offers a promising, chemical-free approach for the efficient and scalable degradation of micropollutants. However, existing piezo-photocatalysts face challenges in optimizing their performance. In this study, oxygen vacancies (OVs) enriched BiOI nanosheets loaded with Ag nanoparticles (NPs) were synthesized to enhance Trimethoprim (TMP) degradation. The 15% Ag-BiOI demonstrated excellent performance, achieving efficiency 97% within 60 min rate constant (k) 0.1157 min–1, which was significantly greater than piezocatalytic (0.0476 min–1) photocatalytic (0.0784 one. synergistic interaction OVs improved O2 adsorption, creating dual active sites (Ag-OV) that promote generation oxidative radicals, such as singlet (1O2) followed by superoxide radical (·O2–) degrade TMP. Likewise, regulated piezoelectric field enhanced TMP providing ample binding surface interaction. acted an electron transport channel, reducing charge carrier recombination, while its plasmon resonance effect modified band gap BiOI, promoting visible light absorption. toxicity assessment showed plasmon-induced piezo-phototronic selectively reduces intermediates converting them into smaller, less-toxic compounds, proposing ecofriendly sustainable micropollutant wastewater treatment.

BiOI is a promising photoelectrocatalyst for oxidation reactions. However, the limited photoelectrocatalytic (PEC) activity necessitates development of new strategies to modify its surface chemistry and thus enhance functional properties. Herein, we present simple method increase photocurrent in BiOI‐based photoanode by exfoliating microspheres oxyhalide produced through hydrothermal synthesis. Following exfoliation isopropanol, resulting layered colloid contains greater variety species, including Bi 2 O CO 3 , I − IO 5+ hydroxides, compared original BiOI. These additional species do not directly PEC oxygen evolution reaction (OER) performance. Instead, they are consumed or converted during OER, more active sites on photoelectrode reduced resistance, which ultimately improves water performance exfoliated Over long‐term chronoamperometry, demonstrates twice as high that microspheres. Analysis after OER reveals combination beneficial charge transfer, enhancing intrinsic properties This study offers insights into role determining performance, aiding optimization 2D materials‐based photoelectrocatalysts.
