Abstract Bifunctional electrocatalysts with high efficiency, stability, and distinguished performance have attracted more attention in the field of overall water splitting, while composition structure design are very essential for superb low price. In this work, heterostructure Mn‐Co‐Fe‐P nanoarrays is situ grown on nickel foam (NF) by simple hydrothermal method phosphating method. The resultant catalyst has favorable electrocatalytic oxygen evolution reaction (OER) overpotential at 10 (100) mA cm −2 192 (279) mV Tafel slope 43.75 dec −1 , hydrogen (HER) 98 (152) 40.68 full voltage 1.66 V 100 when applied to splitting. 3D provides active sites, growth improves stability conductivity catalyst. This binder‐free electrocatalyst excellent catalytic a promising bifunctional candidate
