Abstract

Abstract : A galvanic exchange reaction-mediated one-pot synthesis of Pd–Mn3 O4 nanocomposites for excellent electrocatalytic activity and stability towards the hydrogen evolution reaction. Abstract : Herein, a Mn3 O4 nanooctahedron (NO) supported Pd nanocomposite has been fabricated from a chosen thermodynamically allowed redox transformation reaction. The synthesized Pd–Mn3 O4 (PMO) nanocomposite exhibits outstanding electrocatalytic activity for the hydrogen evolution reaction (HER) in acidic medium with a low overpotential (14 mV), small Tafel slope (42 mV dec −1 ) and high exchange current density (7.74 mA cm −2 ). Moreover, the exceptional durability displayed by PMO on conducting 5000 CV cycles as well as its long-term stability for 36 h (97% activity retention) deserve special attention.
