Burning of carbon-rich substances (such as coal) has been a major source of energy we use today. It not only depletes resources but also adversely impact the environment. With the colloidal graphene quantum dots we are exploring renewable ways to use carbon for energy. Our work in this direction focuses on using the quantum dots for photovoltaics, photocatalytic CO2 reduction and water splitting, and electrocatalytic oxygen reduction reaction (ORR).
