Abstract

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. 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.

具有改良表面几何形状的网状多孔陶瓷二氧化铈结构，用于水和二氧化碳的太阳热化学分解

研究了由二氧化铈制成的网状多孔陶瓷结构的体积吸收集中太阳辐射和驱动H2O和CO2热化学氧化还原分裂的能力。考虑了对RPC(网状多孔陶瓷)暴露表面积的各种几何修改，以提高辐射穿透性并使加热均匀。对结构进行了高通量辐照，测量了其温度分布，分析了其性能，并计算了其氧释放量。研究了由二氧化铈制成的网状多孔陶瓷结构的体积吸收集中太阳辐射和驱动H2O和CO2热化学氧化还原分裂的能力。考虑了对RPC(网状多孔陶瓷)暴露表面积的各种几何修改，以提高辐射穿透性并使加热均匀。对结构进行了高通量辐照，测量了其温度分布，分析了其性能，并计算了其氧释放量。
