Abstract Wide range of noble metal free bimetallic and trimetallic based electrocatalysts have been synthesized to develop efficient oxygen evolution reaction (OER) systems to-date, however, determine which part plays a significant role in controlling OER efficacy remains very challenging. To address this issue, herein we employed machine learning (ML) for the first time element, thus leading development an optimized electrocatalyst. Briefly, designed novel, simple ML sustainable electrocatalyst on Co 3 O 4 /NiO popsicle sticks (CNPS) infused polyaniline/cellulose acetate (a biopolymer) (PNCA) electrospun nanofibers supported nickel foam (NF). CNPS PNCA (CNPS@PNCA) electrode offers maximum homogenous exposition active sites shows high activity by exhibiting low onset potential (1.41 V vs. RHE), overpotential (237 mV at 10 mA cm −2 ) Tafel slope 62.1 dec −1 . Additionally, it better stability more than 100 h is consistent with reported literature.
