Layered transition metal oxides (LTMOs) are a class of two-dimensional materials with transition metal oxides arranged in layered patterns. Their versatility as a platform for energy applications across various sectors has garnered significant interest. This review offers a thorough analysis of the composition and characteristics of LTMOs, as well as their multiple uses in solar-powered water splitting, hydrogen generation, fuel cells, transition metal oxide catalysis, batteries and supercapacitors. LTMOs possess distinctive characteristics, including a significant specific surface area, adjustable electrical properties, and many surface functional sites, which render them extremely appealing for electrocatalytic purposes. The article examines the many uses of LTMOs in batteries, such as lithium-ion, sodium-ion, and potassium-ion batteries. It specifically investigates how different uses affect the structure, composition, and electrochemical characteristics of LTMOs. The text discusses the difficulties and advantages of creating LTMOs, emphasizing important elements including the capacity to be scaled up, maintaining stability over a long period, and effectively incorporating them into real-world devices. In addition, the article examines the possible synergies that may be obtained by combining LTMOs with other materials to improve their electrochemical performance. This review seeks to enhance the development of new materials for clean energy generation, sustainable nitrogen fixation, and high-performance energy storage systems by providing a comprehensive overview of the structure of LTMOs and their applications in energy generation and conversion.
