discovering electrocatalysts for selective and efficient water oxidation and conversion of co2 into fuels

The research in Thrust 1  involves the following themes:

  • Use of theory intertwined with experiment to accelerate discovery of catalysts.

  • Exploration of catalytic motifs that range from simple binary metal alloys to catalytic centers embedded in environments designed to channel reactivity.

  • Establishment of mechanisms to enable optimization of catalysts.

  • Use of high-throughput experimentation coupled with high-throughput screening efforts to discover new materials and help predict their properties.

Thrust 1 Coordinator is Dr. Thomas Jaramillo.
