Rapid synthesis of SrRuO3 using supercritical water fluid with improved oxygen evolution activity

Abstract

Perovskite oxides are typically synthesised using hydrothermal and sol–gel methods, which require long reaction times and can result in broadened nucleation. Herein, we report a rapid, one-step facile synthesis of SrRuO₃ using supercritical water fluid that offers improved oxygen evolution reaction activity compared with the conventional batch hydrothermal method.
