Reticulated porous ceramic ceria structures with modified surface geometry for solar thermochemical splitting of water and carbon dioxide
Reticulated porous ceramic structures made of ceria are investigated for their ability to volumetrically absorb concentrated solar radiation and drive the thermochemical redox splitting of H2O and CO2. Various geometric modifications to the RPC (Reticulated Porous Ceramics) exposed surface area are considered to improve radiation penetration and enable uniform heating. The structures were exposed to high-flux irradiation, their temperature distribution was measured, and their performance was analyzed, including calculation of oxygen release.Reticulated porous ceramic structures made of ceria are investigated for their ability to volumetrically absorb concentrated solar radiation and drive the thermochemical redox splitting of H2O and CO2.
