The hybridization of MoPt with ultralow Pt content (2.81 wt%) on a rutile TiIrO-C composite (MoPt/TiIrO-C) is fabricated by a self-growth-assisted reduction route, serving as an efficient catalyst for the hydrogen evolution reaction (HER). Due to unique structural features, the MoPt/TiIrO-C catalyst requires an extremely low overpotential of 21.35 mV at 10 mA cm and an impressive HER mass activity of 849.36 mA mg at 300 mV overpotential. In addition, the as-made HER electrocatalyst shows superior catalytic stability and chemical after 10 h of testing.
