Researchers in Thrust 3 are synthesizing and characterizing photocatalytic assemblies to elucidate factors governing efficiency, selectivity, and stability, with the aim of providing high performance interfaces for photocatalytic CO2 reduction reaction. They are establishing a pipeline from new materials discovery to integrated (photo) electrochemical assemblies. 

The approach involves the following themes:

  • Understanding of materials interactions and processing sensitivities on performance.
  • Study of the fundamental physics of charge transport  from semiconductors to catalysts in semiconductor/catalyst/electrolyte assemblies. 
  • Establishing approaches for interface engineering that enable desired photovoltages, high charge extraction efficiencies, and durability under operational conditions.
  • Elucidating the role of spatially inhomogeneous and temporally varying potentials on photocatalytic activity, selectivity, and stability.
  • Integration of electrocatalysts into non-planar 3-D morphologies, allowing the interplay between optical absorption, photonic and plasmonic effects.
  • Integration of new materials into functional photoelectrodes with high reproducibility at scales that reduce edge effects and enable failure mechanisms to be captured by experiment.

Thrust 3 Coordinator is Dr. Ian Sharp.
