ENERGY STORAGE: BATTERY & SUPERCAPACITOR
Current electrical energy storage systems such as Li-ion batteries suffer from weak charge/discharge stability, slow charge rate, and explosion risk. To solve these shortcomings, supercapacitor, lithium-sulfur batteries, solid-state batteries are being studied.
CHEMICAL FUEL PRODUCTION (CO2 CONVERSION)
Climate change(global warming) is becoming a big issue all over the world in recent years. Carbon capture and utilization play an essential role to address CO2 emissions. Among all carbon utilization technologies, CO2 electroreduction has gained great interest due to its potential for directly converting CO2 to a variety of valuable chemicals by using clean renewable energy. To achieve an effective and selective conversion of CO2, high-performance nanocatalyst technology is of great importance. Our research is focusing on the synthesis of composite materials and nanocatalysts for electrochemical chemical fuel production.
PHOTOCATALYSIS
Generating hydrogen from water is one of the promising next-generation energy technology. Because increasing environmental pollution is causing irreversible damage in our world, this must be prevented.
Photocatalysts can produce hydrogen fuel from water by using sunlight as a power source. Hydrogen generation and consumption closed loop can make an efficient and eco-friend energy cycle. It is the reason for studying the photocatalyst in terms of energy production.
FUEL CELLS & WATER ELECTROLYSIS
Alloyed metal, metal, and non-metal based catalysts can be used for energy conversion reactions such as oxygen reduction reaction(ORR) oxygen evolution reaction(OER), hydrogen evolution reaction(HER), etc.
Platinum is a state-of-the-art catalyst especially in fuel cells because of its excellent catalytic ORR performances. Most recent works broadly use various Pt-based materials such as PtCo, PtNi, PtFe alloys, and core-shell Pt nanoparticles. To make highly active but cost-effective fuel cell catalysts, reducing the amount of Pt in the catalyst is essential.
