About

Dr. V. Navakoteswara Rao is a materials scientist and postdoctoral researcher specializing in photocatalysis, photoelectrochemistry, electrocatalysis, and sustainable hydrogen production. Born on May 14, 1990, in Nagulapadu, Tirupati District, Andhra Pradesh, India, he has built an international research career focused on advanced catalytic materials for solar-fuel generation, water splitting, and alkaline natural-seawater electrolysis. His research centers on the rational design of nanostructured and multimetallic catalysts, heterointerfaces, high-entropy materials, MXene-based heterostructures, layered double hydroxides, and core–shell architectures. He combines materials synthesis with electrochemical analysis, in situ and operando spectroscopy, and computational approaches to determine how composition, defects, interfaces, and atomic-scale structure influence catalytic activity, selectivity, and stability. His goal is to translate fundamental catalyst design into durable materials for practical renewable-energy technologies.
Dr. Rao earned a B.Sc. in Mathematics, Physics, and Chemistry from Sri Venkateswara Arts College, affiliated with Sri Venkateswara University, Tirupati, in April 2011. He completed an M.Sc. in Analytical Chemistry from Sri Venkateswara University in April 2014 and a B.Ed. in Physical Science and Mathematics Methodology from Sri Krishnadevaraya University in November 2015. His academic achievements include All India Rank 43 in Chemical Sciences in the 2014 CSIR-UGC NET examination. He also qualified GATE 2018 with a score of 340 and an All India Rank of 3361.He began his research career as a Junior Research Fellow in the MNRE–YVU–CECRI project at Yogi Vemana University, working in the Nano-Catalysis and Solar Fuels Research Laboratory under Prof. M. V. Shankar. His doctoral research focused on hierarchical nanostructured photocatalysts for solar-driven hydrogen production through water splitting. A significant component of this work involved using industrial-waste-derived substrates, particularly hydrogen sulfide and crude glycerol, for sustainable solar-fuel production. This research addressed environmental remediation and clean-hydrogen generation while building his expertise in photocatalyst design, heterostructure engineering, charge transfer, and solar hydrogen evolution. After working as a Senior Research Fellow, Dr. Rao received his Ph.D. in Materials Science and Nanotechnology from Yogi Vemana University on March 17, 2021. He subsequently continued his research in South Korea as a Senior Researcher at the National Nanofab Center, KAIST, where he contributed to advanced nanomaterials and energy-related research. He was supported by the Brain Pool Fellowship from July 2021 to December 2023, expanding his international experience in nanotechnology and sustainable-energy materials. From January 2024 to February 2025, Dr. Rao served as a Postdoctoral Researcher at Jeju National University under Prof. Kim Sang-Jae, focusing on advanced catalytic materials and electrochemical energy conversion. Since March 2025, he has been a Postdoctoral Researcher in the Department of Chemistry at the Korea Advanced Institute of Science and Technology, Daejeon, Republic of Korea, under Prof. Tae Kyu Kim. At KAIST, his work includes sustainable Photocatalysis, electrocatalysis, high-entropy catalysts, MXene-based materials, layered double hydroxides, core–shell nanostructures, and natural-seawater electrolysis. He employs operando Raman spectroscopy, X-ray absorption fine-structure spectroscopy, X-ray photoelectron spectroscopy, differential electrochemical mass spectrometry, advanced electrochemical characterization, and density functional theory calculations. These tools reveal the dynamic evolution of catalytic active sites and establish relationships among material structure, reaction pathways, performance, and durability.
Dr. Rao has authored more than 50 peer-reviewed publications, including high-impact journal articles, book chapters, and conference contributions. His research has received more than 3,600 citations, with an h-index of about 36 and an i10-index of about 52. His publications cover photocatalytic hydrogen production, photoelectrochemical water splitting, hydrogen and oxygen evolution, high-entropy materials, MXene-derived catalysts, seawater electrolysis, and catalytic mechanisms. His contributions have been recognized through the Brain Pool Fellowship, Inno-CORE Fellowship, Young Scientist Award at Nano Korea, and presentation awards at international conferences. He has also been included among the World’s Top 2% Scientists in the Stanford–Elsevier ranking and serves as a reviewer for peer-reviewed journals. Through interface engineering, composition and defect control, and operando–computational analysis, Dr. Rao aims to advance scalable materials and technologies for renewable hydrogen, solar-to-fuel conversion, and carbon-neutral energy systems.
