Direct Air Capture and Conversion of CO2 using Moisture-Activated,
Oxidatively Stable Porous Mixed-Metal Hydroxides

The goal of this project is to demonstrate, for the first time, direct air capture (and conversion) under ambient conditions using high-performing solid sorbents that are purely inorganic in composition. The project will seek to demonstrate the synthesis, characterization, and temperature swing adsorption performance of highly porous mixed metal hydroxides on which carbonate species are stabilized through solvation by hydration layers that are formed under conditions typically encountered
during DAC applications.

Funding Cycle: 2023-2024

Focus Area(s): Direct Air Capture (DAC), Carbon Conversion
