Porous ceramics with different pore size and pore distribution can be utilized in wide range of energy and environmental applications including membranes, filtrations, insulations, catalysts, catalyst supports, absorbers, sensors and light weight structural components, often together with hierarchical pore structures. To fully take advantage of the vast potential of porous ceramics, oxide and non-oxides types, the manufacturing routes, which can be coupled with numerical approaches, used to design such components play a key role. Therefore, this symposium will include the recent progresses in the design, processing, characterization, properties and modeling of porous ceramics. These ceramic materials contain pore sizes from the nanometers to millimeters, and can have textured to random porosity or hierarchical porosity and are based on various pore architectures, such as foams, honeycombs, fiber networks, bio-inspired structures, membranes, aero-gels, composites, and additive manufacturing. This symposium will be the ideal showcase for the recent research interests and activities, covering the areas from inorganic chemistry to material science, modeling and simulation. The advanced industrial applications can include energy and environmental related technologies such as energy generating, energy conversion and/or saving, environmental protection technologies, sensors, catalytic supports, gas filtration, application engineering and mass separation.
