Dr. Siraj Sultan received his PhD in Chemistry from the Ulsan National Institute of Science and Technology (UNIST), South Korea, in 2020. His doctoral research focused on the development of advanced electrocatalysts and electrolyzer systems for hydrogen (H₂) production through water splitting, contributing to the advancement of clean and sustainable energy technologies. During this period, he developed strong expertise in materials synthesis, electrochemical reaction engineering, and system integration under both acidic and alkaline conditions. Following his PhD, Dr. Siraj worked as a Postdoctoral Researcher (2020–2022) and subsequently served as a Research Assistant Professor (2022–2026) at UNIST. During this period, he significantly expanded his research portfolio beyond water splitting into: (1) Electrochemical CO₂ reduction (eCO₂R) toward C₂+ products (2) Electrochemical nitrogen reduction chemistry, including nitrate reduction (NO₃R) to ammonia and C–N coupling reactions for sustainable urea synthesis (3) Reaction pathway engineering to enhance selectivity and suppress competing hydrogen evolution reaction (HER) (4) Integration of catalyst design with membrane-electrode assembly (MEA) electrolyzer systems His work emphasizes atomic-level catalyst engineering, carbon and nitrogen utilization efficiency, and scalable reactor design for sustainable fuel and chemical production.
