Speech Title: Iridium Oxide and Iridium-Ruthenium Oxide for Oxygen Evolution
Abstract: Hydrogen can be produced using proton exchange membrane water electrolysis. In this process, water is split to give oxygen, electrons and protons at the anode. These protons pass through the membrane and are reduced at the cathode to hydrogen gas. The anodic reaction requires the largest overpotential and therefore limits the current efficiency of water electrolysis. In acidic conditions IrO2 based catalysts are the most active. Here we discuss catalysts for the oxygen evolution reaction consisting of both pure IrO2 and of mixed IrO2-RuO2 catalysts. Structure and activity of mixed catalysts prepared in different ways is demonstrated. Structure and activity of mixed catalysts when supported on conductive doped SnO2 is also discussed. The nature of the electronic structure of electrochemically formed iridium oxide films (EIROF) is investigated by in-situ conductivity measurements in an electrochemical cell and ex-situ current-sensing atomic force microscopy (CS-AFM). This work expands our fundamental knowledge of the mechanism of action of these catalytic materials and brings the technology closer to more energy efficient electrolytic production of hydrogen for a sustainable transport fuel option.

Prof. Josip Brnić, University of Rijeka, Croatia
Biography: Professor Josip Brnić, D. Sc., was born in 1951. on the Island of Krk, Croatia. Primary and secondary education was acquired on the island of Krk. He graduated in Mechanical Engineering at the Faculty of Engineering, University of Rijeka (Croatia). He received his master’s degree at the Faculty of Mechanical Engineering, University of Ljubljana (Slovenia) and his doctoral degree at the Faculty of Engineering, University of Rijeka (Croatia). Currently he is professor with tenure at the Faculty of Engineering, University of Rijeka. One period, at the beginning of his career (12 years) he worked in parallel as a university professor at the Faculty of Engineering at the Department of Engineering Mechanics and in the project organization "Brodoprojekt" Rijeka on structure analyzes of submarines and other floating objects. He was Vice-Dean and Dean (two mandates) of the Faculty of Engineering of the University of Rijeka, Vice-Rector and Rector of the University of Rijeka. He was a member of the National Council for Science of the Republic of Croatia (two mandates), and President of the Scientific Council for Engineering Sciences of the Republic of Croatia (three mandates). Also, he is an Associate member of the Croatian Academy of Sciences and Arts. Apart from being active at the Faculty of Engineering, University of Rijeka, he is teaching also on doctoral study at the Faculty of Mechanical Engineering Slavonski Brod / Croatia. He gave a number of lectures at the Harbin Institute of Technology (Harbin / China), Tai-Yuan University (Tai- Yuan / China), Huazhong University of Science and Technology (Wuhan / China), Shanghai University (Shanghai / China), Shenyang University of Technology (Shenyang / China) as well as at Henan Polytechnic University (Jiaozuo / China). His scientific researches are focused primarily on two essential points, the first of which is numerical analysis of structures and machines using finite element method and the second referring to the experimental analysis of the material behavior of structure subjected to different environmental conditions, i.e., to different stress levels and differenet temperatures (lowered and elevated temperature regime), creep and fatigue. He is a mentor to candidates for doctoral theses, masters and diploma theses. He is a reviewer of scientific papers for several prestigious international journals indexed in Current Contents as well as many books. He speaks English and uses German and Slovenian.
