title: A new stable Pd-Mn3O4 nanocomposite as an efficient electrocatalyst for the hydrogen evolution reaction.
abstract: Herein, a Mn3O4 nanooctahedron (NO) supported Pd nanocomposite has been fabricated from a chosen thermodynamically allowed redox transformation reaction. The synthesized Pd-Mn3O4 (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.
