porieus

Porieus is a term used in materials science to describe porous solids with interconnected networks that extend across multiple length scales. These networks produce high surface area and enable rapid transport of fluids and gases, which is valuable in adsorption, filtration, and catalysis.

Porieus materials can be inorganic, organic, or hybrid composites. They typically exhibit multi-scale porosity, including micropores, mesopores, and macropores. The connectivity and uniformity of the pore network influence mass transport, mechanical strength, and surface chemistry.

Common synthesis routes include hard templating, soft templating, and self-assembly, followed by drying and activation steps to stabilize porosity and tailor pore sizes. Post-synthesis modifications may introduce functional groups to enhance selectivity.

Key properties include large surface area, adjustable pore size distribution, and tunable chemical functionality. Limitations can include structural fragility, aging, and pore collapse under extreme conditions.

Applications span gas storage and separation (such as CO2 capture and hydrogen storage), heterogeneous catalysis, energy storage and conversion (supercapacitors and batteries), water treatment, and chemical sensing.

The concept of porieus has grown out of advances in zeolites, porous polymers, and metal-organic frameworks. The term has appeared in theoretical discussions and research proposals since the early 2000s.
