Herein, the stability and reversibility of anionic redox reactions are enhanced by a simple sulfur-assisted surface modification method, which not only modulates the material's energy band allowing feasible electron release from both bonding and antibonding bands, but also traps the escaping Oⁿ ^- via an as-constructed SnS_2- _x _- _σ O_y coating layer and return them to the host lattice upon discharge. The regulation of anionic redox inhibits the irreversible structural transformation and parasitic reactions, maintaining the specific capacity retention of as-modified cathode up to 94% after 200 cycles at 100 mA g^-1 , along with outstanding voltage stability. The reported strategy incorporating energy band modulation and oxygen trapping is promising for the design and advancement of other cathodes storing energy through anion redox.23:T4ce,Bifunctional electrocatalysts with high efficiency, stability, and distinguished performance have attracted more and more attention in the field of overall water splitting, while the composition and structure design are very essential for electrocatalysts with superb performance and low price. In this work, the heterostructure Mn-Co-Fe-P nanoarrays is in situ grown on nickel foam (NF) by simple hydrothermal method and phosphating method. The resultant Mn-Co-Fe-P catalyst has favorable electrocatalytic performance with the oxygen evolution reaction (OER) overpotential at 10 (100) mA cm^-2 of 192 (279) mV and the Tafel slope of 43.75 mV dec^-1, the hydrogen evolution reaction (HER) overpotential at 10 (100) mA cm^-2 of 98 (152) mV and the Tafel slope of 40.68 mV dec^-1, and the full voltage of 1.66 V at 100 mA cm^-2 when applied to overall water splitting. The 3D heterostructure provides more active sites, and the in situ growth improves the stability and conductivity of the catalyst. This binder-free heterostructure electrocatalyst with excellent stability and catalytic performance is a promising bifunctional electrocatalyst candidate for overall water splitting.
