THRUST 2: PHOTOELECTROCATALYSIS AND LIGHT CAPTURE

 

accelerating the discovery and in-depth understanding of photocatalysts and photoactive material for solar-driven co2 reduction reaction.


The research in Thrust 2 involves the following themes:

  • Use of experiment and theory to accelerate the identification of semiconductor materials with appropriate band energetics for efficient photocatalysis.
  • Development and characterization of materials for protection of light absorbers to achieve robust photocatalysis with large photovoltage.
  • Understanding and control of catalytic activity and selectivity at the surfaces of photoactive materials.
  • Design of photonic motifs to enhance light harvesting and photocatalysis.

Thrust 2 Coordinator is Dr. John Gregoire
