The rational design of cost-effective electrocatalysts for the hydrogen evolution reaction (HER) still remains a major challenge in continuable energy storage and conversion systems. In this study, vertically hollow ultrathin Mo-doped CoP (Mo-CoP) nanoarrays are prepared on nickel foam by hydrothermal low-temperature phosphating strategies. Mo-CoP possess bamboo-leaf structure with diameter ranging from 20 to 150 nm between top bottom length several microns. At same time, substance presents crystalline–amorphous structure. synergistic effect doping special construction can supply plentiful active sites, enhance electrolyte penetration, facilitate gas diffusion process electrocatalytic reaction. overpotentials electrode at 10 mA cm–2 as low 88.4, 78.7, 112.6 mV, Tafel slopes 87.2, 55.7, 120.3 mV dec–1 alkaline, acidic, neutral electrolytes, respectively. Moreover, catalyst also displays favorable long-term stability all pH ranges.
