Dr. Stjepko Krehula
Stjepko Krehula received his PhD degree in physical chemistry from the Faculty of Science, University of Zagreb in 2006. He works as a senior research associate in the Division of Materials Chemistry at the Ruđer Bošković Institute in Zagreb. His main area of research is the synthesis of nanostructured iron oxides (and other metal oxides) using hydrothermal synthesis methods, their characterization using 57Fe Mössbauer spectroscopy and other techniques (PXRD, SEM, EDS, TGA, UV-Vis, FT-IR, Raman, SQUID, XANES, EXAFS) and their application in photocatalysis, electrocatalysis and polymer composites. His research is particularly focused on the study of the influence of doping with different metal cations on the structural, thermal, magnetic, vibrational, optical, photocatalytic and electrocatalytic properties of iron oxide nanoparticles. Since 2019, he has been teaching the postgraduate course “Spectroscopic methods in materials research” at the Faculty of Chemical Engineering and Technology, University of Zagreb.
