Herein, a facile and controllable synthesis strategy for nickel–cobalt bimetal phosphide nanotubes as highly efficient electrocatalysts for overall water splitting via low‐temperature phosphorization from a bimetallic metal‐organic framework (MOF‐74) precursor is reported. By optimizing the molar ratio of Co/Ni atoms in MOF‐74, a series of Co x Ni y P catalysts are synthesized, and the obtained Co4Ni1P has a rare form of nanotubes that possess similar morphology to the MOF precursor and exhibit perfect dispersal of the active sites. The nanotubes show remarkable hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalytic performance in an alkaline electrolyte, affording a current density of 10 mA cm −2 at overpotentials of 129 mV for HER and 245 mV for OER, respectively. An electrolyzer with Co4Ni1P nanotubes as both the cathode and anode catalyst in alkaline solutions achieves a current density of 10 mA cm −2 at a voltage of 1.59 V, which is comparable to the integrated Pt/C and RuO 2 counterparts and ranks among the best of the metal‐phosphide electrocatalysts reported to date.20:T4f9,Low-cost transition-metal dichalcogenides (MS₂) have attracted great interest as alternative catalysts for hydrogen evolution. However, a significant challenge is the formation of sulfur-hydrogen bonds on MS₂ (S-H_ads), which will severely suppress hydrogen evolution reaction (HER). Here we report Cu nanodots (NDs)-decorated Ni₃S₂ nanotubes (NTs) supported on carbon fibers (CFs) (Cu NDs/Ni₃S₂ NTs-CFs) as efficient electrocatalysts for HER in alkaline media. The electronic interactions between Cu and Ni₃S₂ result in Cu NDs that are positively charged and can promote water adsorption and activation. Meanwhile, Ni₃S₂ NTs are negatively charged and can weaken S-H_ads bonds formed on catalyst surfaces. Therefore, the Cu/Ni₃S₂ hybrids can optimize H adsorption and desorption on electrocatalysts and can promote both Volmer and Heyrovsky steps of HER. The strong interactions betwee
