Designing electrocatalysts with high‐performance potential requires a thorough investigation of the relationships between property changes and electrocatalytic activity. This study compares effect N‐doping N, S‐codoping on properties waste floral foam derived pristine nanoporous carbon to enhance modulates textural, structural, chemical that are preferable oxygen evolution reaction (OER) hydrogen (HER) performance. S‐codoped having large surface area (1231 m 2 g −1 ), higher content defects, OH−, CO, pyridinic N exhibits superior OER HER activity overpotentials 290 −180 mV, respectively at 10 mA cm −2 , emphasizing synergetic dual atoms nitrogen (N) sulfur (S) in enhancing The work proposed here presents implementation “waste‐to‐energy” through repurposing into as metal‐free bifunctional electrocatalyst for HER.
