摘要

Energy is the most basic necessity of contemporary world, and water splitting is well known renewable energy source. Creating an efficient, outstanding performance, as well as durable electrocatalyst has grown into major goal for improving water-splitting efficacy. A solvothermal approach was employed to synthesize a non-toxic, eco-friendly, and inexpensive CuMoO4/PANI electrocatalyst to enhance oxidation of water. Several analytical techniques were used to determine the compositional, textural, morphological, and thermal characteristics of CuMoO4/PANI. The electro-chemical properties of CuMoO4/PANI have been studied Using a 3-electrode configuration in 1 M KOH, revealing unusually low overpotential (244 mV) at optimal current density (10 mA/cm²). The electrochemical surface area (ECSA) value of 266.25 cm² and notable stability of around 30 h indicate that synthesized electro-catalyst demonstrates exceptional capability for OER. Subsequent analysis indicated a notably reduced Tafel (39 mV/dec), implying that CuMoO4/PANI has enhanced electro-catalytic efficacy as well as rapid reaction kinetics. The CuMoO4/PANI demonstrates the substantial potential for water electrolysis and electrochemical applications due to its extensive surface area, diverse active sites, remarkable durability, quick electron movement, reduced resistivity, and advantageous conductive properties.
