摘要

Currently, the world is facing a serious energy issue, and the only well-known source of energy is fossil fuels but the quick depletion of fossil resources has caused significant concerns. It is concerning that the overuse of gas and coal for energy generation is contaminating our ecology and environment. To solve this issue, it is crucial to investigate renewable options for energy generation. One of most favourable method for manufacturing renewable energy is water splitting. Catalysts are crucial in water electrolysis; in the current study, CaMnO3/PANI composite is employed as an electrocatalyst for OER. The CaMnO3/PANI composite’s stability and strong catalytic activity make it an exceptional electrocatalyst for water splitting. Physical technique like X-ray diffraction and scaning electron microscope were used to identify structural and morphology of CaMnO3/PANI, which was manufactured by hydrothermal methods. Electrochemical potential of manufactured materials was analyzed in 1 M KOH used as electrolyte (having a pH of 13.6), the nanocomposite CaMnO₃/PANI exhibited remarkable OER capabilities, such as a lower overpotential (234 mV) and Tafel slope (50 mV dec−1). Electrocatalyst not only facilitates electron transport but also demonstrates extended durability even after 2550 cycles. These findings demonstrated that CaMnO3/PANI electrocatalyst is great choice for OER.
