Developing a clean and sustainable energy future while preserving our environment is one of the crucial aspects in the age of anthropocene. Decarbonizing our carbon footprint is indispensable. In the Ong research group, we are interested in the development of energy nanomaterials. Our research emphasizes 4 major thrusts: (1) Photocatalysis and photoelectrocatalysis (2) Electrocatalysts for energy conversion (3) Thermal catalysis for energy and environmental science (4) Beyond Li-ion batteries
