THRUST 1: ELECTROCATALYSIS
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.
