Formation of an iron-containing nanostructured surface of glassy carbon and verification of its catalytic properties

Abstract

Atmospheric pollution with carbon dioxide is a serious environmental threat to the climate of our planet. We can find a way to solve it using the method of electrochemical reduction of CO2. This article presents the research results during which data were obtained on the formation of an iron-containing nanostructured surface of a glassy carbon electrode using the methods of electrochemical deposition and scanning electron microscopy, during which it was concluded that the longer the pectate complex with iron is deposited on the surface of the working electrode, the greater number of particles formed on its surface. The catalytic properties of the PG-NaFe complex in water were also tested using cyclic voltammetry when the solution is saturated with carbon dioxide. It was experimentally proved that the iron-containing complex PG-NaFe exhibits catalytic activity for the carbon dioxide reduction reaction in the course of this research. Method for the deposition of a sodium pectate complex with iron on the surface of a glassy carbon electrode without the use of expensive components was proposed based on the analyzed data.
