As our reliance on eco-friendly and renewable energy grows, there is an urgent need to explore various sustainable sources. In this race, solar energy is considered an enormous energy source that can offer a permanent solution to the world's energy crisis. However, a few hours of sunshine in a day, uneven power density distribution on the earth due to geographical area, and low power conversion efficiencies of photovoltaic devices threaten its widespread acceptability. Of several other renewable energy resources, splitting water to generate hydrogen as a fuel and oxygen as a byproduct is the most viable technique. However, in several electrochemical reactions, the energy conversion rate and efficiency are often limited by oxygen evolution reaction (OER) expressed as equation (1) in aqueous media. This reaction proceeds via multiple state reactions involving 4 electron oxidation, thus becoming kinetically sluggish. Therefore, to kinetically accelerate this reaction, the overpotentials (η) need to be lowered. Thus, several OER electrocatalysts exhibiting lower η have been explored so far. 4𝑂𝑂𝑂𝑂 -→ 2𝑂𝑂 2 𝑂𝑂 + 4𝑒𝑒 -+ 𝑂𝑂 2 ; 𝐸𝐸 = 1.23 𝑉𝑉 𝑣𝑣𝑒𝑒𝑣𝑣𝑣𝑣𝑣𝑣𝑣𝑣 𝑅𝑅𝑂𝑂𝐸𝐸
