N2 - In this research, La2CuO4-decorated ZnO was designed by in situ nanoparticle fabrication using Strobilanthes crispus (B.) leaves extract (SLE) for the first time. To investigate the properties, La2CuO4-decorated ZnO were characterized by various characterization techniques. By a modification with La2CuO4, ZnO possesses the improved photocatalytic activity for malachite green degradation under visible-light illumination. ZnO-La2CuO4 nanocomposites exhibit high photocatalytic activity compared to ZnO and La2CuO4. The improved photocatalytic activity can be ascribed to the effect of the decreased bandgap value of the nanocomposite structure due to the low recombination of photogenerated electron-hole pairs. Furthermore, ZnO-La2CuO4 shows good stability after three-run of photocatalysis experiment. The present research offers an eco-friendly and cost-effective method as an alternative for ZnO-La2CuO4 nanocomposites fabrication with excellent photodegradation performance.
