Electrochemical Energy Conversion
Oxygen Evolution Reaction I Oxygen Reduction Reaction | Hydrogen Evolution Reaction
The basic goal of electrocatalysis is to identify the ideal electrocatalysts and conditions that will enable the required reactions to occur most effectively, or with the less overpotential. Fuel cells require catalysts as the kinetics of the chemical reactions involved make them somewhat slow. Nanomaterials based on carbon and non-nobel metals are created, and their activity towards diverse fuel cell reactions is studied. Electrocatalysis plays a crucial role in various energy conversion processes, particularly in reactions such as the Oxygen Reduction Reaction (ORR), the Oxygen Evolution Reaction (OER), and the Hydrogen Evolution Reaction (HER). These reactions are fundamental to the operation of fuel cells, electrolyzers, and batteries.
Sustainable Energy Harvesting
Piezocatalysis
A developing method for producing "Green Hydrogen" that can address a number of the shortcomings of photocatalytic and electrocatalytic methods is piezocatalytic water splitting. Our goal is to create such piezocatalytsts that can split water with an incredibly high efficiency even without the aid of a cocatalyst or scavenger to concurrently produce H2 and value-added H2O2.
Photocatalysis
Carbon quantum dots (CQDs) are a class of carbon compounds that show photoresponse and have a wide range of possible applications. The quantity of molecular oxygen that is absorbed by dissolved CQDs from the air can be controlled by light irradiation. Polyethylene-derived carbon dots (CD) have numerous potential uses and provide workable ways to lessen plastic pollution. Its great aerial oxygen-harvesting properties allow oxidation reactions to proceed in both air and oxygen with same efficiency. This makes it possible to employ free air as an oxidant, and their "autophagous" or self-eliminating nature makes disposal easier.
