Sustainable energy conversion and Innovative Technologies for a particular material
Renewable energy conversion techniques include the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). However, their applications are severely limited because these processes need more energy to activate and have sluggish kinetics. Noble metal-based compounds like Ru, Rh, and Ir have long been the most promising catalysts for eliminating such barriers. For example, RuO2 and IrO2 are commonly used as benchmark catalysts for complete water splitting. On the other hand, Pt-based materials are more practical for the HER but perform badly in the OER. Due to their high cost and low tolerance, these valuable electrocatalysts have been recommended to be limited for practical usage and commercialization. This enormous demand drives scientists to develop a unique bifunctional catalyst that is acceptable, low-cost, long-stable, economically feasible, and performs better. Various materials such as porous carbon (PC), metal oxides (MO), and metal-organic frameworks (MOF) have been a major area for energy storage, clean energy, catalysis, capacitor, etc. MOF-based catalysts may be fabricated using functional group-containing organic ligands, including active heteroatoms from the periodic table such as carbon, oxygen, nitrogen, boron, and sulfur. Furthermore, a MOF may be utilized as a crowd to incorporate and encapsulate guest species such as metal centers, polyoxometalates (POMs), and metal Nano-particles by leveraging the intrinsic properties of pure MOFs utilizing the post-synthesis approach. Similarly, the pristine MOF can be employed as a precursor or template for forming a coordination complex by high-temperature calcination or pyrolysis. These well-designed MOF precursors are chemically rehabilitated into equivalent inorganic metal compounds through pyrolysis or hydrothermal treatment. Nonetheless, their distinct morphologies are preserved to produce diverse nanostructures by altering the reaction environment and reactants. Furthermore, a material part is used to control the trouble of working with other materials in catalysis and ecologically energy conversion applications.
The following potential research topics are expected for this special issue:
1) metal oxide and carbon composites fabrication is derived from a metal-organic framework.
2) Energy conversion by converting hazardous chemicals with a cost-effective electrocatalyst.
3) Electrochemical water splitting using novel metal oxide and carbon composite electrode materials.
4) Study of different electrode materials toward water-splitting reaction.
