Two dimensional (2D) materials and their composites are now in trends due high electrocatalytic activity and ion storage capacity. The development of cost-effective and simple electrocatalyst for energy applications are still challenging. The best substitute to typical Transition metal oxides/hydroxides/chalcogenides (TMOs/TMHs/TMC) for electrocatalysis is Transition metal based Layer Double Hydroxide (TM-LDH). Layer Double Hydroxide materials have various benefits, including low cost, chemical composition variety, easily manipulated characteristics, a wide range of preparation variables, unique anion exchange and intercalation properties, chemical stability, and colloidal and thermal behaviour. But the fewer active sites and poor electronic conductivity of Layer Double Hydroxide restricts their applications. Here, the proposed work has the purpose to contribute to the expansion of electrocatalysts that are effective in a variety of energy applications. The main focus is to develop hierarchical structure of Layer Double Hydroxide, composition of Layer Double Hydroxide/Transition metal chalcogenides and Layer Double Hydroxide/carbon based materials adopting various methods such as hydrothermal/solvothermal, liquid phase exfoliation and electrodeposition. The technique appears to eliminate hurdles related to electrical/ionic conductivity and surface morphology, resulting in a bifunctional/trifunctional electrocatalyst that is effective for wearable supercapacitor and overall water splitting.
