Sergii has obtained his PhD in Physical Chemistry in 2015 from L.V. Pisarzhevskii Institute of Physical Chemistry of the National Academy of Sciences of Ukraine, focusing on structure, sensor and electrophysical properties of tin oxide nanocomposites. During PhD work, he also participated in several projects dealing with investigating the functional properties of zeolites and nanocomposites based on porous SiC. In 2007-2013 he was involved in a collaborative project with Pillar JSC company (manufacturer of silicon wafers for solar cells). After completing the PhD, Sergii contributed to the research in various groups. In 2015-2016 he was a post-doc at Nazarbayev University, Republic of Kazakhstan, Astana, and took part in a research project in the area of SERS sensors. In 2016 he obtained a grant for young scientists at the National University of Science and Technology (MISiS), Russia, Moscow with project focused on development of novel doped CeO2-based electrolytes for solid oxide fuel cells. In 2019-2023 Sergii work at University of Aveiro, CICECO – Aveiro Institute of Materials, Portugal. His research currently focus mainly on the synthesis and characterization of MXene-based materials as electrocatalysts for hydrogen evolution, electrodes for supercapacitors and photocatalysts.
