Research Themes
Research Summary

Research Interests


A “CLEAN” vision for next generation–Green energy & Sustainable environment – Electrochemical Energy Storage and Conversion (Batteries, Fuel-cells, Supercapacitors and Water-splitting electrolysers,), Catalysis, CO2 capture & conversion, Hydrogen storage, Methane storage and Pollutant capture. The materials under investigations include nanoporous solids of metal-organic frameworks (MOFs), carbons of biomass, polymer, graphene/graphene-oxide and MOF-derivatives, family of hydrogen storage materials (metal/alloy hydrides, complex hydrides & porous solids), and layered & membrane/thin-film structures.

Developing advanced functional nanoporous solids by pre- & post-synthesis modification and hybrid framework structures to enhance the structure-property relationship for “Clean Energy & Sustainable Environment”. We probe materials with wide range & complementary characterizations, include: 1) low-temperature molecular adsorption of N2, H2, CO2, & CH4 (specific surface area, pore-size distribution, pore-volume and molecular uptake and separation capacity), 2) combined thermogravimetric & mass spectroscopy (structure property), 3) high-pressure (up to 200 bar, H2, CO2, & CH4 storage by uptake isotherms) & variable temperature gas uptake measurements by volumetric and gravimetric methods (high capacity energy storage), 4) selective molecular adsorption & purification by column/membrane based mass spectroscopy/chromatography, and 5) complete electrochemical electrode materials tests (oxygen reduction reactions, Oxygen evolution or water oxidation, Water splitting or hydrogen evolution, supercapacitors, & meal-air batteries).
