Dr. Pandurangan Vijayalakshmi | Polymer Chemistry | Women Researcher Award
Department of Chemistry, Tamilnadu Open University | India
Dr. Vijayalakshmi P is an emerging researcher in environmental chemistry, nanomaterials, photocatalysis, and electrochemistry, with a strong publication record and interdisciplinary research experience. Her doctoral work focused on the design and synthesis of advanced semiconductor-based nanocomposites and their photocatalytic degradation efficiency toward hazardous organic pollutants, including antibiotics, pesticides, and dyes. She has developed a wide range of Z-scheme and heterojunction photocatalysts such as V₂O₅/g-C₃N₄/ZnO, Bi₂O₃/g-C₃N₄/ZnO, TiO₂/g-C₃N₄/CuFe₂O₄, and ZrO₂-based composites, demonstrating significant improvements in visible-light-driven degradation performance. Her research extends to energy storage materials, supercapacitors, electrochemical sensing, and CO₂ reduction, reflected in her contributions to high-impact journals including Ionics, ChemistrySelect, Electrochimica Acta, Langmuir, and Emergent Materials. She has also collaborated on studies involving nanostructures for sensing carbendazim, biocompatible nanoscaffolds, and spinels for antibacterial and dielectric applications. Skilled in multiple analytical and characterization techniques XRD, SEM, TEM, UV–Vis, PL, EIS. she integrates materials synthesis with mechanistic and kinetic studies to address real-world environmental challenges. Her international exposure includes a research internship at the National Taipei University of Technology. Recognized with the Visionary Research Scientist Award (2025), she continues to advance innovative solutions for environmental remediation and sustainable energy applications.
