Abstract Hydrogen, a sustainable alternative to fossil fuels, can be efficiently produced by electrochemical water splitting, which involves hydrogen evolution reaction (HER) at the cathode and oxygen (OER) anode. Both HER OER require electrocatalysts. The large scale implementation of this technology depends heavily on development highly active, stable, cost‐effective In view this, several electrocatalysts have been explored. Herein, electrocatalytic performance MnCO 3 synthesized hydrothermal method is reported. While chosen as electrocatalyst owing cost‐effect abundant precursors, environmental friendliness, good activity, for its simplicity, efficiency, scalability. micron size hydrothermally exhibits η 10 143 mV, Tafel slope 72 mV dec −1 retains over 3000 cycles 14 h continuous operation in 0.5 M H 2 SO 4 , demonstrating utility production.
