General information

The research activity of the Department of Electrochemistry is related to such applied topics, as metal- composite materials, electrochemical capacitors, fuel cell elements and enzyme-based biological sensors. As to the fundamental side of the department research, it is achieved due to performing development of adequate models of charge transfer in materials with mixed electronic and ionic conductivities. This creates some basis, which makes it possible to develop new methods for studies and design of the materials in question.

History

The Department of Electrochemistry of Saint-Petersburg State University was founded by Prof. Rudolf L. Muller in 1940. After the Second World War the department was leaded by Profs. Boris P. Nicolsky (1950), and Alexey V.Storonkin (1951-1952). Prof. Yaroslav V. Durdin have been a chairman during subsequent twenty years (1952 – 1973). His research intersts were mainly focused on the kinetics of hydrogen evolution from acidic solutions. During the next twenty years (1973 – 1994) the department had been headed by Prof. Valery I. Kravtsov. In this period, the main attention in the department research was paid to electrode processes involving metal complexes with different ligands. Prof. Valery V. Malev was the head of the Electrochemistry Department during 1994-2013. At this time the experimental and theoretical work was focused on the study of charge transfer processes at chemically modified electrodes.

Department personalities

Professor Veniamin V. Kondratiev became the head of the Department of Electrochemistry in 2013. His research interests are Electrochemistry, Spectroelectrochemistry, Redox and Conducting Polymers, Nanocomposite Materials, Metal Nanoparticles, Multilayered Coatings, Material Technology, and Sensors.

Prof. V. Kondratiev reads a series of lections in electrochemistry and has a great experience in design, preparation, and characterization of new multifunctional pristine and nanocomposite polymer coatings that might be used for different applications. During the recent years his research interests have been focused on syntheses of conducting polymer films and metal-containing ones, which can be used for electrocatalytical, energy saving, and electroanalytical purposes. The polymer modification strategies used can lead to a variety of such desirable effects, as three-dimensional dispersion of redox mediators within modifying films, fast catalytic responses of the developed electrodes due to improving the transport properties of covering films, resulted from a close proximity of the included metal particles and conducting sites of a polymer lattice, and high mechanical and chemical stability of the modifying inclusions within the film matrix. The main results of these investigations are reflected in references [8, 12-19] given below.

Professor Valery V. Malev

Prof. V. Malev reads four cycles of lections destined for students of the Chemical faculty, namely Electrochemistry (students of the 3-rd course), Electrochemical Methods (students of the 4-th course of the physical chemistry profile), Modified Electrodes, and Electrochemistry of Membranes (both cycles for students specializing in electrochemistry). He carries out a common guidance of scientific research performed by his department colleagues and guides post-graduate studies. He is a permanent coordinator and researcher of grants supported by the Russian Foundation for Basic Research and the Saint Petersburg University, and an author of numerous papers (more than 150) published in peer-reviewed journals. His most important publications devoted to migration currents and double layer structural effects (refs. [1-3]), modeling of biological and artificial membranes (refs. [4-6]), charge transfer processes on electrodes modified with electroactive polymer films (refs. [7-11]) are given below. Experimental and theoretical results obtained along the last topic are summarized in monograph “Polymer-Modified Electrodes” (V.V. Malev, V.V. Kondratiev, A.M. Timonov, “Nestor-History”, SPb, 2012).

Valery I. Kravtsov

Prof. V. Kravtsov reads lecture courses concerning the electrochemistry of metal complexes for bachelor and master students. His preceding research works are summarized in monographs “Electrode processes in solutions of metal complexes” (LGU, Leningrad, 1969) and “Equilibrium and kinetics of metal complexes electrode processes” (Khimia, L., 1985).

Associated professors

Vladimir D. Ivanov

Ass. Prof. V. Ivanov is responsible for special courses for master students.

Oleg V. Levin

Ass. Prof. O. Levin became a permanent member of the department in 2010 after his work as a researcher in Li-ion Battery Department of Samsung SDI Company, South Korea. His research interests are connected with electrochemical power sources and polymeric metal complexes.

The projects carried out in his group are devoted to studies of activated carbon materials for double layer capacitors and polymeric materials for hybrid faradaic-double layer capacitors. The fundamental significance of such research is determined with elucidation of charge transfer mechanisms within the films possessing a mixed redox and conjugated conductivity [9-11, 20-22].

He reads lections on Electrochemistry for bachelor students and Electrode materials for lithium-ion batteries for master students, conducts laboratory works with students mastered the course of Electrochemistry, and leads the students’ diploma projects.

Ass. Prof. Tamara G. Nikiforova

The research interests of Ass. Prof. T. Nikiforova are now connected with new catalysts for the alcohols’electrooxidation processes in fuel cells. She reads special courses of lections for bachelor and master students.
