Determination of doping strategy on the electrochemical performance of the hydrothermally prepared perovskite material

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.
