Abstract

Clean energy from renewable resources has attained more and more attention in recent years, because of this, there has been a shift in emphasis towards creating renewable, environmentally benign and economically viable alternatives to fossil fuels. However, finding an effective and long-term electrocatalyst for enabling OER in electrochemical water splitting is extremely sought after of this significant challenge. In this study, straightforward and efficient sonication method was employed to produce Sm-doped MnSnO₃ as an electrocatalyst for OER. Furthermore, electrocatalytic properties of Sm-doped MnSnO₃ was quite impressive, with least overpotential (η) of 210 mV needed to attain current density (C_d) of 10 mA cm⁻². In addition, Sm-doped MnSnO₃ electrocatalyst demonstrates least Tafel slope with value of 32 mV dec⁻¹. Further, Sm-doped MnSnO₃ electrocatalyst also exhibits remarkable stability and low impedance characteristics, resulting in improved performance in oxygen evolution reaction (OER). These findings suggest that the current Sm-doped MnSnO₃ has great potential as an electrocatalyst for facilitating the OER in hydrogen energy production.

期刊介绍： The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
