Abstract Sodium‐sulfur (Na─S) batteries have drawn considerable research interest owing to their high theoretical energy density and nature abundance. However, the intrinsic sluggish kinetics that has so far been scarcely explored in conversion reaction of sodium polysulfides (NaPS) hinders its practical application. Herein, design strategy heterointerfaced nanoreactor is presented as sulfur reduction (SRR) electrocatalyst for room temperature Na─S batteries. The synergistic incorporation heterointerface confined structure can modulate electronic transitional metal active site upshift d‐band center, leading enhanced NaPS adsorption catalytic toward streamlined SRR. Moreover, spatial confinement not only stockpile nanoparticles avoid agglomeration detachment, but also effectively immobilize species inhibit shuttle effect accommodate volume expansion over sodiation. as‐developed achieve discharge capacity 1310 mAh g −1 , remarkable cycling stability 2500 cycles, excellent performance under loading lean electrolyte/sulfur ratio.
