Herein, a novel S-Scheme LaNiO3/g-C3N5 photocatalyst was designed and fabricated to eliminate pollutants in aquatic environments. The LaNiO3/g-C3N5 sample with 30 wt% LaNiO3 over g-C3N5 (30LN/CN) manifested superior photocatalytic activity for treating tetracycline antibiotic (TC). Specifically, the 30LN/CN catalyst achieved up to 90.0 % of TC removal after 60 min irradiation under a UV 395 nm light source, with a degradation rate constant of 6.3 x 10- 2 min- 1, which was 1.4 and 3.5 times higher than those of individual g-C3N5 and LaNiO3, respectively. Antibacterial activity of treated TC solution using 30LN/CN catalyst completely loss in a short time. Moreover, the 30LN/CN sample showed its high adaptability under realistic simulated environmental conditions and excellent performance in removing various pollutants. Remarkably, the catalyst retained its efficiency even after five consecutive reuse cycles, highlighting its durability and stability. The enhanced photo- catalytic activity was attributed to the S-scheme charge transfer mechanism, which facilitated efficient charge separation and transfer while suppressing the photogenerated electron-hole recombination rate. This work offers a viable approach to construct photocatalytic heterojunctions for addressing antibiotic contamination in water systems.
