The created scientific bases and regularities of electrochemical formation of ordered nano- and micro-level materials of hemotronics are based on a clear separation of the influence of the charge transport mechanism of the limiting stage of the electrochemical process on the stratification of the structure of the surface oxide and metal phases of the electrode. The structuring of semiconductor phases is governed by the ratio of gradients of the electric field and charge carriers in liquid and solid phases.
Developed gas diffusion catalytically active 3D-electrodes based on valve metal having a two-level three-dimensional structure comprising a microporous composite electrocatalytic coating applied to a discontinuous basis, and a porous regular of the electrode structure, which may include both electrocatalytically active material, and a mixture of the latter with other disperse materials.
The scientific foundations of corrosion micro- and nano-structured materials in electrochemical systems, sensors and supercapacitors, which are based on the new classification of corrosive processes. Scientific novelty create a foundation is in the experimental and theoretical justification identifying the crucial role of corrosion processes on the kinetics of electrode processes under extreme operating conditions these systems.
Created an electrochemical gas sensor NTUU "KPI" for determining hydrogen sulfide, which endowed of high resolution and selectivity and can be use for manufacturing automation, quality control, safety, security and anticorrosive protection of the environment. Made a set of theoretical and experimental studies to determine the kinetic parameters of the redox reactions and mass transfer in electrochemical systems is based on solid and electrolyte matrix to enhance the selectivity and resolution and cost savings generated by sensors.
