dcterms:description
Layered misfit chalcogenide structures have garnered much attention and prestige in several applications such as thermoelectric materials and high-temperature superconductors. However, its potentials for important electrochemical applications such as hydrogen evolution and oxygen reduction reactions have not been systematically studied. Till date, such applications have mainly applied precious metal and oxides with perovskite- or spinel-based structures. In this work, we synthesized a misfit layered mixed oxide in the form of Ca3Co4O9 and investigated its structural, morphological, and electrochemical properties. The misfit layered Ca3Co4O9 has promising capabilities as electrocatalyst for hydrogen evolution and oxygen reduction processes. A Tafel slope of 87 mV/decade for hydrogen evolution reaction was achieved by Ca3Co4O9, while the overpotential for oxygen reduction reaction was lowered up to 38 mV in comparison to glassy carbon. Moreover, a comparably higher heterogeneous electron transfer rate of 3.76 x 10(-4) cm s(-1) was achieved for Ca3Co4O9 compared to 3.11 x 10(-4) cm s(-1) for glassy carbon. The affordability and electrocatalytic properties have endowed Ca3Co4O9 as a potential replacement for precious metal in electrocatalysis and electrochemical sensing applications.
