Abstract

This study presents an efficient and cost-effective technique for the fabrication of perovskite-based materials such as lanthanum cobalt oxide (La-1), silver-doped lanthanum cobalt oxide (La-2), and silver-doped lanthanum cobalt oxide nanocomposite with carbon nanotubes (La-3) aimed to improve their photocatalytic activities against two model pollutants pendimethalin pesticides and methylene blue dye under solar irradiation. The synthesized materials were analyzed using the X-ray diffraction (XRD) technique, Fourier transforms infrared (FTIR) and UV–visible spectroscopy, confirming the successful formation of all nanomaterials and providing detailed insight into their crystalline structure, chemical composition, optical properties and photocatalytic activities. Tauc plots were used to determine the bandgaps of the synthesized catalysts, revealing values of 3.41 eV for La-1, 3.11 eV for La-2, and 2.76 eV for La-3. La-3 showed enhanced catalytic activity against pendimethalin (77.14 %) and MB (87 %). These findings underscore the potential of the La-3 sample as an effective photocatalyst for treating organic effluents in environmental remediation.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
