Electrochemical properties of layered SnO and PbO for energy applications

Abstract

In this paper we synthetized four different lead oxides with tetragonal or orthorhombic symmetry either by thermal decomposition or a chemical route. Another two tin oxides were also synthesized by thermal decomposition and chemical route respectively. We analysed their structure by XRD and SEM and chemical composition by EDS and XPS. Thermal decomposition was analysed using STA. The surface areas were determined by BET. Electrochemical behavior such as heterogeneous electron transfer rate, electrocatalytic properties in hydrogen evolution and oxygen reduction reactions were also investigated by cyclic voltammetry and linear sweep voltammetry. Results suggest that studied materials are promising candidates for catalysis or various applications in energy management.
