Amelioration of Perovskite Nanomaterials for Advance Energy Applications

The demand of energy highlight the need to explore new energy resources with less emissions without depleting the environment. With this perspective, novel perovskite lead-free materials are taking over the conventional energy systems of fossil fuels that produce carbon in the environment. It has been years of struggle that scientists are working on materials for more energy with less waste materials. The challenge was readily accepted by perovskite nanomaterials that can generate energy, store it, and use it when required. The development of these nanomaterials with their promising properties such as dielectric coefficient, superconductivity, and sustainability at high temperatures, withstand high mechanical properties and can be coated, pasted, or in the form of thin and thick films. This can be done by the solidstate reaction (SSR) mixing the metallic oxides in a fixed ratio in ball milling by wet or dry method. The composites prepared were calcined, pressed, and sintered at high temperatures. Following the characterization to check the properties make them superior for high-energy advanced applications. The perovskite nanomaterials’ composites can be utilized perfectly for hydrogen generation and production, photocatalysis reactions, photovoltaic solar cells, solid oxide fuel cells, electrolysis, supercapacitors, sensors, actuators, structural health monitoring applications and metal-air batteries. This chapter covers the application-based synthesis, characterizations, and properties of the perovskite nanomaterials for high-energy applications.
