Biography

Janusz Nowotny earned his Ph.D. in solid state chemistry at the Institute of Physical Chemistry, Polish Academy of Sciences, 1967, and obtained Sc.D. degree (habilitation) from the AGH University of Science and Technology, Krakow, in materials science. His research is focused on mass and charge transport in ionic solids. His work aims at the development of photosensitive oxide semiconductors for solar energy conversion and electrochemical gas sensors.

He has been visiting professor at University of Bourgogne, Max-Planck-Institute for Solid State Research, University of Nancy, University of Marseille and Tokyo Institute of Technology. He obtained the US NSF award to support a major international project on oxide semiconductors (1974-78) and was a research coordinator of the international project on zirconia supported by the New Energy Development Organization, NEDO (1994-97).

He was the director of NATO Advanced Research Workshop on Nonstoichiometric Compounds, 1988. He received the award of the International Association for Hydrogen Energy, 2008, for outstanding research contributions in the development of TiO2-based systems for solar hydrogen production. He published over 460 refereed papers and 17 books in the area of solid state electrochemistry

Areas of Research / Teaching Expertise

• Solid-state chemistry solid-state electrochemistry
• Oxide semiconductors
• Photoelectrochemistry and photocatalysis
• Materials for electrochemical energy conversion
• Science and technology of titania (TiO2)
• Solar energy technologies

The research includes the formation and characterization of novel photosensitive oxide semiconductors of controlled charge transfer, electronic structure and reactivity, for a wide range of applications, including photoelectrochemical water splitting, solar water disinfection, as well as anti-pollution and anti-corrosive coatings. The research strategy is based on in situ monitoring of surface and bulk semiconducting quantities during the formation of the oxide systems at elevated temperatures as well as the determination of the charge transfer during gas/solid reactions. The main achievements include the determination of surface vs. bulk defect chemistry and the related semiconducting quantities as well as the determination of the reactivity of oxygen and water with oxide semiconductors.
