Preparation of transition metal oxides and mixed metal oxides via a microwave‐assisted method that permits processes to be completed in a quicker reaction time with the formation of homogenous and well‐dispersed nanoparticles. Recently, due to the environmentally friendly nature of this technique, it has become an important approach to green chemistry. The major advantage of microwave‐assisted synthesis includes clean, fast, efficient, less time‐consuming, highly accelerated rate, high yield, and an economic method. In this review, we have discussed the process of microwave synthesis and also compared this with other synthetic methods. A discussion of transition metal oxides in groups was performed where we have discussed their synthetic route and reaction conditions along with the effect on morphology and other properties. Additionally, the application of transition metal oxides as supercapacitors was also discussed. Since then, researchers have gained a lot of interest in transition metal oxides as energy storage devices due to their low‐cost, energy efficient, long cycle life, and improved electrical, thermal, and chemical stability, variable oxidation states and excellent redox properties. However, they cannot meet the need for high‐performance energy devices due to their low conductivity.
