Research Interests

Electro-organic Synthesis: We are exploring the integration of Physical Chemistry and Organic Synthesis through the use of Proton-Coupled Electron Transfer (PCET). PCET (concurrent transfer of proton and electron) is a fundamental process in nature, as it lowers the kinetic barrier for reactions to occur. We have uncovered novel mechanisms of PCET and demonstrated that the core structures of natural products can be synthesized using various PCET pathways. An example of this is the dimerization of 3-substituted-2-oxindole, which we achieved through four different kinetic pathways (See below image).

Heterogeneous Electrocatalysis: We are exploring heterogeneous electrocatalysis such as water oxidation, hydrogen evolution reaction etc. Three specific targets are (a) improving the active sites for catalysis, (b) enhancing the chemical stability of electrocatalysts and (c) employing in-situ techniques to understand the mechanisms of catalysis. An example of nanomesh catalyst for water oxidation has been shown below. 

Solid-State Proton Conduction: In 2016, we first demonstrated solid-state proton conduction in Functionalized Graphene bypassing the theoretical limitations. Since then, we have systematically enhanced the proton conductivity of graphene-based materials. Our goal now is to demonstrate the potential of functionalized graphene as a fuel cell membrane, offering a cost-effective alternative to expensive Nafion. At the same time, we aim to deepen our fundamental understanding of the mechanisms behind proton conduction.

Electrochemical Supercapacitor: We are developing carbon-based materials for supercapacitor applications to enhance energy storage science. Our approach incorporates fundamental chemistry principles, including Proton-Coupled Electron Transfer (PCET), to advance energy storage technology.
