Rapid synthesis of SrRuO 3 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.
